Answer:
x^2 + 2x +1 = 2x + 2
Step-by-step explanation:
(x+1) = 2
multiplying both sides by x +1
(x +1) (x+1) = 2 (x+1)
x^2 + 2x +1 = 2x + 2
Answer:
12.124-3
Step-by-step explanation:




4(x + 15) > = 120
4x + 60 > = 120
4x > = 120 - 60
4x > = 60
x > = 60/4
x > = 15...........so ur answer is 15 or more
#3 is not a function because there are two answers for one out put
#4 is a function because it is a straight line
The answer is c because you had to simplify the roots in order to get your answer it’s basic math
