Start with x2 + 4x = 12 and complete the square, what is the equivalent equation?
A) (x + 2)2 = 16
B) (x + 2)2 = 14
C) (x + 4)2 = 16
D) (x + 4)2 = 28

How can you solve an equation with a variable on both sides? complete the explanation. you can solve the equation by using *(blank)* operations to get the variable terms on one side of the equal sign and the constant terms on the *(blank)* side. then *(blank)* both sides by the coefficient of the resulting variable term.

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit

Which expression gives you the distance between the points (5,1)and(9,-6)
