Answer:
cool
Step-by-step explanation:
The perimeter of a rectangle is 2(l+b)
Breadth =" b " is the same thing as width
so if the width is half the length it will be = 1/2w
Final answer = 2(l + 1/2w)
l stands for length
hope u get this right

What does the graph tell you about the solution to the system equation?
Answer:
Step-by-step explanation:
The two lines intersect at one point. At this one point, the two students will have drunken the same amount of liquid.
There is sufficient info here so that one could determine that time and that volume of liquid if desired.
Write the equation of the line passing through the points (-7,9) and (7,5).
Answer:
[tex]y=-\frac{2}{7} x+7[/tex]
Step-by-step explanation:
First Solve For The Slope Using The Two Given Points!
M = Slope
M = [tex]\frac{y2-y1}{x2-x1}[/tex]
M = [tex]\frac{5-9}{7--7}[/tex] Two negative signs together makes addition!
M = [tex]\frac{-4}{14}[/tex] Move the negative sign (only if the fraction has a negative)
M = [tex]-\frac{4}{14}[/tex] Simplify
M = [tex]-\frac{2}{7}[/tex] Final Answer
Then see how many units the graph goes up = y-intercept

Use the FOIL method to find the product.
(5x-8)(2x + 6)
Answer: 8
Step-by-step explanation:
Answer:
10x² + 14x - 48
Step-by-step explanation:
F: (5x)(2x) = 10x²
O: (5x)(6) = 30x
I: (-8)(2x) = -16x
L: (-8)(6) = -48
combine the two middle terms to get 14x
10x² + 14x - 48

Which equation represents y = x2 + 12x + 27 in vertex form?
y = (x + 6)2 − 9
y = (x + 6)2 + 21
y = (x + 6)2 + 9
y = (x + 6)2 + 27
Answer:
y = (x + 6)² - 9Step-by-step explanation:
Complete the square:
y = x² + 12x + 27
= x² + 2*6*x + 6² - 6² + 27
= (x + 6)² - 36 + 27
= (x + 6)² - 9
Correct choice is A
find the remainder
PLSS HELP!

The remainder is 24
Step-by-step explanation:
[tex]\frac{3x^4-2x^2+5x-6}{x+2}=[/tex]
[tex]3x^3+\frac{-6x^3-2x^2+5x-6}{x+2}=\\[/tex]
[tex]3x^3-6x^2+\frac{10x^2+5x-6}{x+2}=[/tex]
[tex]3x^3-6x^2+10x+\frac{-15x-6}{x+2}=[/tex]
[tex]3x^3-6x^2+10x-15+\frac{24}{x+2}[/tex]
Therefore, the remainder is 24.

write an exponential function in the form y = ab^x that goes through points (0,20) and (8,5120)
9514 1404 393
Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x

What do all rectangles have in common? Choose ALL the correct answers.
no sides
the same length

the same length
4 sides
4 right angles
Answer:
4 right angles
Step-by-step explanation:
All rectangles have 4 right angles in common.
All the rectangles have all their right angles (there are four of them) in common. The bottom-left box correctly states the commanality.
What is a rectangle?A rectangle consists of 4 sides, connected end to end, such that all the adjacent sides are at right angles (90°) with each other.
Due to four corners in a rectangle, and all corners internally having right angles, so all the rectangles have 4 right angles in common.
It isn't necessary for all the four sides being equal (its for square though, a special case of rectangles). (we assume that the fourth box is stating that all 4 sides of all rectangles are same in length)
But all the rectangles have their oppositely faced side pairs having equal length within their pairs.
Also, even if all the rectangles have 4 sides, but one rectangle can have some other lengthed sides, and another rectangle can have its sides of other lengths.
Thus, all the rectangles have all their right angles (there are four of them) in common (well right angle is not the only thing they've got in common, like they've got exterior angles common, 4 vertices etc). The bottom-left box correctly states the commanality.

Use the side -splitter theorem to solve for x in the triangle below
Answer:
x = 30
Step-by-step explanation:
Side splitter theorem,
"If a line intersects two sides of a triangle and is parallel to the third side of the triangle, will divide the sides proportionally."
Therefore, ratio of the parts of two sides intersected will be proportional.
[tex]\frac{3}{15}= \frac{6}{x}[/tex]
[tex]x=\frac{6\times 15}{3}[/tex]
[tex]x=30[/tex]
Therefore, [tex]x=30[/tex] will be the answer.
