The school spent 100 dollars in all wow that's a lot tell me if you got the right answer when you turn ur test in
Answer:
x < 3
Step-by-step explanation:

Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
They are equal to one another because 4(3+x) can be rewritten using the distributive property as 4(3)+4x or 3+3+3+3+x+x+x+x
The length is 3 times longer than the width (7)
3 x 7 = 21
the length is 21.
To find perimeter, add all sides together:
21 + 21 + 7 + 7 = 42 + 14 = 56
56 ft is your answer
hope this helps
