answer : ??help plz thank u

Answer 1

This is the writing section. We don't know much about math, here.

Answer 2

You just put the 3 in for the x so the expression becomes:

11 + (8 - 3)^2 - 20 (then you use PEMDAS, so parenthesis first)

11 + (5)^2 - 20 (5^2 is 25)

11 + 25 - 20 (Addition or Subtraction next)

36 - 20 = 16 (16 is your answer)
