If f(x) = -7x+5x^2+10, what does f(-2) equal?

f(x) = -7x + 5x² + 10

f(-2) This means that x is -2, so you plug in -2 for "x" in the equation

f(x) = -7x + 5x² + 10

f(-2) = -7(-2) + 5(-2)² + 10

f(-2) = 14 + 5(4) + 10

f(-2) = 20 + 24

f(-2) = 44

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
