y=-3x-5

y=4x+9
y=-3x-5

y=2x+5
y=x-1

y=2x+5
y=5x+11

y=3x+7
y=-x -1

step-by-step explanation:

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
