Fred was told to simplify (3x + 2)2. His work is below. (3x + 2)2 = (3x)2 + (2)2 = 9x2 + 4

Part A: Explain what mistake Fred made while doing the problem.

Part B: What is the correct answer to the problem Fred was given?

Fred did not first simplify what was inside of the parentheses. He should've simplified that first, because of PEMDAS.

Step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
