Answer:
80 square yards
Step-by-step explanation:
We know we have a width of 8 yards and a perimeter of 36.
how I figured it out was:
36=(8*2) * (x*2)
8*2=16
36-16=10
So now we know the length and width.
area of a rectangle is lw (length * width)
10*8=80.
A. Because the paint depends of the cubes
(I’m pretty sure)
Answer:
C
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
=
= - 
the y- intercept is the value of y where the line crosses the y- axis , then
y- intercept = 2
There’s two ways to substitute, but i think you mean if you know x but don’t know y. if that is true, then yes use substitution
