Answer:
Fourth option
Step-by-step explanation:
The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.
Hope this helps.

A scale model of the empire state building is 8cm tall. The actual building is 1454 feet tall. What scale factor was used to create the scale model?
Answer:
Scale Factor [tex]= 5540[/tex]
Step-by-step explanation:
As we know -
Scale scale factor [tex]= \frac{L_p}{L_m}[/tex]
[tex]L_p =[/tex] Length of Actual object
[tex]L_m =[/tex] length of the model
Substituting the given values in above equation we get
Scale factor
[tex]= \frac{44317.92}{8} \\= 5539.74\\=5540[/tex]

Ash is 4 years younger than Gary, and Oak is 5 times Gary's age. The sum of their three ages is 94. Find Gary's age. Show working out. Thanks!!
Answer:
Step-by-step explanation:
If Gary's age is 14 then
Ash is 4 years younger = 14 - 4 = 10
And Oak is 5 times Gary's age = 14 x 5 = 70
So total ages = 70 + 14 + 10 = 94

Given \(\triangle DEF\ :\ \triangle RST\), find the scale factor.
Answer: The required scale factor[tex]=\dfrac43[/tex]
Step-by-step explanation:
Formula : [tex]\text{Scale factor }=\dfrac{\text{Side in image}}{\text{Corresponding side in pre-image}}[/tex]
Here, ED = 3 units in Δ DEF which corresponding to SR = 4 units in ΔRST
Now,
Scale factor for the given transformation = [tex]\dfrac{SR}{ED}[/tex]
[tex]=\dfrac{4}{3}[/tex]
hence, the required scale factor[tex]=\dfrac43[/tex]

a case of fruit weighs 53 kilogram and another weighs 47 kilograms how much weight must be removed from the first case and placed in the second is that they both equal
a . 2 kilograms
b . 4 kilograms
c . 6 kilograms
d . 8 kilograms
There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Fruit weight = 53 kilograms
And, Another weight = 47 kilograms
Now,
Let number of kilograms weights to remove and add = x
So, We can formulate;
⇒ 53 - x = 47 + x
Solve for x as;
⇒ 53 - 47 = x + x
⇒ 6 = 2x
⇒ 2x = 6
⇒ x = 3
Thus, There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

Answer:
Option 3
Step-by-step explanation:
the symbol your question is showing is "greater than or equal to"
when a line includes "or equal to", the circle will be filled in. also, since the symbol is going towards 5, it is considered a greater than symbol. so, you'd want to choose the option with a filled in circle and an arrow pointing to the right.
since option 3 has a filled in circle and has its arrow pointing towards the positive (or right) side of the line, it should be option 3.

Ms.Maxwell bought a purse with 1/4 of her money. The purse cost $37.00. How much money did Ms.Maxwell have left after she bought the purse?
Answer:
the money left after purchasing the purse is $111
Step-by-step explanation:
The computation of the money left after purchasing the purse is given below:
Since in the question it is mentioned that she bought a purchase with one-fourth of money
And, the purse cost is $37
So the amount left would be
= $37 × (3 ÷ 4) ÷ (1 ÷ 4)
= $37 × 0.75 ÷ 0.25
= $111
Hence, the money left after purchasing the purse is $111

Elijah is planning a circular flower garden with a 12 foot diameter. He will put plastic edging along the flowerbed. How many feet of edging will Elijah need to enclose his flower garden? Round to the nearest tenth place. (Use 3.14 for π)
Answer:
[tex]37.7\ \text{foot}[/tex]
Step-by-step explanation:
The length of the edging will be equal to the circumference of the circular flower garden.
Here, the diameter of the circular garden is [tex]d=12\ \text{foot}[/tex]
Circumference of a circle is given by
[tex]C=\pi d\\\Rightarrow C=3.14\times 12\\\Rightarrow C=37.68\approx 37.7\ \text{foot}[/tex]
The length of the edging is [tex]37.7\ \text{foot}[/tex].
7. Expand and reduce A(x). Then calculate A(x) for x=1.
A (x) = (3x – 3)(3x + 2)
Given:
The function is
[tex]A(x)=(3x-3)(3x+2)[/tex]
To find:
The simplified form of A(x) and value of A(x) at x=1.
Solution:
We have,
[tex]A(x)=(3x-3)(3x+2)[/tex]
[tex]A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)[/tex]
[tex]A(x)=9x^2+6x-9x-6[/tex]
[tex]A(x)=9x^2-3x-6[/tex]
Putting x=1, we get
[tex]A(1)=9(1)^2-3(1)-6[/tex]
[tex]A(1)=9-3-6[/tex]
[tex]A(1)=9-9[/tex]
[tex]A(1)=0[/tex]
Therefore, the simplified form of A(x) is [tex]A(x)=9x^2-3x-6[/tex] and the value of A(x) at x=1 in 0.
