Which expression is equivalent to x ^2 – 8x + 16? (x – 4) ^2
(x - 8)(x + 2)
(x + 4) ^2
(x – 4)(x + 4)

Step-by-step explanation:

x^2 - 8x + 16 = (x - 4)^2

the first one

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
