Find (2x – 7)2
a. 4x4 – 49
b. 4x4 - 14x2 + 49
c. 4x4 – 28x2 + 49
d. 4x2– 28x – 49

its D i think you did a mistake for the answer is

4x^2 - 28x + 28

hope this helps

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

pi x^2

step-by-step explanation:

pi times x squared
