What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
2x² + 7x + 6x² + x - 64x² - 9x² - 5x + 6
Combine all like terms.
(2x² + 6x² - 64x² - 9x²) + (7x - 5x) + 6
(8x² - 73x²) + 2x + 6
-65x² + 2x + 6
There are no common factors or like-terms to simplify.
So,
The simplified form is -65x² + 2x + 6
Thus,
The simplified form of the complex expression 2x² + 7x + 6x² + x - 64x² - 9x² - 5x + 6 is
-65x² + 2x + 6

Which of the following quadrilaterals must be a parallelogram according to the minimum requirements?
Answers
The minimum requirements needed to be a parallelogram is found in Option A quadrilateral, thus Option A is our correct answer.
There are four quadrilaterals given in the option.
We need to check which quadrilateral has the minimum requirements.
What is the minimum requirement to construct a parallelogram?The construct a Parallelogram we need:
- The measure of any two non-parallel sides.
- The measure of an angle.
In a Parallelogram, opposite sides are equal and parallel and the opposite angles are equal.
Checking the options given.
Option A:
- Two parallel and equal sides.
- Equal opposite angles.
It meets the minimum requirement to be a parallelogram.
Option B:
The quadrilateral has only two parallel and equal sides.
It does not meet the minimum requirements to be a parallelogram.
Option C:
The quadrilateral has only one parallel and equal side.
It does not meet the minimum requirements to be a parallelogram.
Option D:
It has no parallel and equal sides.
It has equal opposite angles and diagonal bisecting.
But it does not meet the minimum requirements to be a parallelogram.
We see that the minimum requirements needed to be a parallelogram is found in option A,
Hence Option A is our correct answer.

Which statement is true about whether Z and B are independent events?
Z and B are independent events because P(Z∣B) = P(Z).
Z and B are independent events because P(Z∣B) = P(B).
Z and B are not independent events because P(Z∣B) ≠ P(Z).
Z and B are not independent events because P(Z∣B) ≠ P(B).
Answers
Answer:
Z and B are independent events because P(Z∣B) = P(Z).
Step-by-step explanation:
After a small online search, I've found a table to complete this problem, that we can see below.
For two events Z and B, we have:
P(Z|B) = probability of Z given that B
such that:
P(Z|B) = P(Z∩B)/P(B)
So, two events are independent if the outcome of one does not affect the outcome of the other.
So, if the probability of Z given B is different than P(Z) (the probability of event Z) means that the events are not independent.
So Z and B are independent if the probability of Z given B is equal to the probability of Z.
P(Z|B) = P(Z)
In the table we can see:
P(Z|B) will be equal to the quotient between all the cases of Z given B (126) and the total cases are given B (280)
P(Z|B) = 126/280 = 0.45
Similarly, we can find P(Z):
And P(Z) = 297/660 = 0.45
So we can see that:
P(Z|B) = P(Z)
Thus, B and Z are independent.

We have to assume that ABCD is a parallelogram. If it isn't, leave a note.
Secondly we have to assume that the angles are consecutive. In a parallelogram, consecutive angles are supplementary.
<A + <B = 180
2x + 5 + 3x - 15 = 180
5x - 10 = 180 Add 10 to both sides
5x = 190 Divide by 5
x = 190/5
x = 38
A = 2x + 5
A = 2*38 + 5
A = 81
B = 3x - 15
B = 3*38 - 15

Given a leading coefficient of 8, polynomial roots of 1 & 2, and the known point on the graph (4,5). Write an equation that will find the
missing 3rd root (r). You do not have to solve the problem. See the example "Find the Missing Root - Interesting Twist" if you need help.
_=_(_-1)(_-2)(_-_)
Answers
Given:
The leading coefficient of a polynomial is 8.
Polynomial roots are 1 and 2.
The graph passes through the point (4,5).
To find:
The 3rd root and the equation of the polynomial.
Solution:
The factor form of a polynomial is:
[tex]y=a(x-c_1)(x-c_2)...(x-c_n)[/tex]
Where, a is a constant and [tex]c_1,c_2,...,c_n[/tex] are the roots of the polynomial.
Polynomial roots are 1 and 2. So, [tex](x-1)[/tex] and [tex](x-2)[/tex] are the factors of the polynomial.
Let the third root of the polynomial by c, then [tex](x-c)[/tex] is a factor of the polynomial.
The leading coefficient of a polynomial is 8. So, a=8 and the equation of the polynomial is:
[tex]y=8(x-1)(x-2)(x-c)[/tex]
The graph passes through the point (4,5). Putting [tex]x=4,y=5[/tex], we get
[tex]5=8(4-1)(4-2)(4-c)[/tex]
[tex]5=8(3)(2)(4-c)[/tex]
[tex]5=48(4-c)[/tex]
Divide both sides by 48.
[tex]\dfrac{5}{48}=4-c[/tex]
[tex]c=4-\dfrac{5}{48}[/tex]
[tex]c=\dfrac{192-5}{48}[/tex]
[tex]c=\dfrac{187}{48}[/tex]
Therefore, the 3rd root on the polynomial is [tex]\dfrac{187}{48}[/tex].

Answer:
3.8; 4
Step-by-step explanation:
In this exercise, you're are required to find the missing values by performing some arithmetic calculations.
For the first part;
Let the missing value be X
Translating the word problem into an algebraic expression, we have;
[tex] X = 2000 * 1.9 * 10^{-6} [/tex]
[tex] X = 3.8 * 10^{-3} [/tex]
For the second part;
Let the missing value be Y.
[tex] 3.8 * 10^{-3} = Y * 9.5 * 10^{-4} [/tex]
[tex] X = \frac {3.8 * 10^{-3}}{9.5 * 10^{-4}} [/tex]
[tex] X = 4 [/tex]
Therefore, the complete sentence would be written as follows;
[tex] 3.8 * 10^{-3} [/tex] is 2000 times greater than [tex] 1.9 * 10^{-6} [/tex]. It is also 4 times greater than [tex] 9.5 * 10^{-4} [/tex]

Answers
Answer:
x ÷ 1/4
Step-by-step explanation:
Concepts:
An expression a mathematical sentence that has at least two numbers and a minimum of one math operation (addition, subtraction, etc.) in it. An expression cannot have an = sign in it.A variable is an unknown, numerical value in an equation, often represented by the letter x.Solving:
Let's translate the first part of the expression:
1. "A number"
Since we're unaware of the number in this expression, we can mark it as a variable, x.This means that, so far for our expression, we only have the variable, "x".2. "divided by 1/4"
When we're dividing, we use the ÷ symbol to represent that operation. Now, let's put the first part of our expression with the second one: "x ÷ 1/4"Therefore, the expression for this situation is x ÷ 1/4.
Mrs.Click has a strawberry patch in her garden. It's border is 4/5 meters wide and 3/2 meters long. What is the area of Mrs.Clicks Garden?
Answers
Answer
Mrs. Click's Garden is 6/5 or 1 1/5 square meters.
Explanation
Mrs. Click's has a rectangular garden. To find the area of a rectangle, you multiply the width by the length. To find the area of Mrs. Click's Garden, you multiply 4/5 by 3/2.
To multiply fractions, you multiply the numerator by the denominator.
4×3 is 12 and 5×2 is 10. You get the fraction 12/10, which can be simplified to 6/5, or 1 1/5.

Can you guys help me find ST on the left and WY on the right
Answers
Answer:
ST = 17 and WY = 32
Step-by-step explanation:
3
SV is a perpendicular bisector and divides Δ RST into 2 congruent triangles with
ST = SR , that is
7x - 4 = 3x + 8 ( subtract 3x from both sides )
4x - 4 = 8 ( add 4 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Then
ST = 7x - 4 = 7(3) - 4 = 21 - 4 = 17
-------------------------------------------------------------------
4
Δ WXY and Δ WXZ are congruent ( both have 3 congruent angles ), then
WZ = WY , that is
9x - 13 = 6x + 2 ( subtract 6x from both sides )
3x - 13 = 2 ( add 13 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
WY = 6x + 2 = 6(5) + 2 = 30 + 2 = 32
