Use y=mx+b
m = 4
x = 0
y = -1
-1 = (4)(0) + b

Answer: Distributive property of the multiplication.
Step-by-step explanation:
You did not post Gretchen's expression, but i gues that it is 3*(x + y)
I guess that it is the distributive property of the multiplication.
For 3 numbers, A, B and C, we have that:
A*(B + C) = A*B + A*C
here we have:
3*x + 3*y
We can do the inverse process to the distributive property, and get:
3*x + 3*y = 3*(x + y)
which i guess is Gretchen's expression.
The surface area of a cylinder is:
A=2pr^2+2prh
A=2pr(r+h) we are approximating π as 3.14, r=12, and h=8 so
A=2(3.14)12(12+8)
A≈1507.2
A≈1507 m^2 to nearest m^2
A /b = 4 +c so the answer is 40
