D. 6x+2


Evaluate the expression 4y^2 - 2x / 7 + 2y For X=7 and Y=2

A. 2

B. 4 2/7

C. 5

D.18

Answer 1

7(2x - 4) + 2(3x + 1) Distribute/multiply 7 into (2x - 4), and multiply 2 into (3x + 1)

14x - 28 + 6x + 2 Combine like terms

20x - 26

Your answer is B

`4y^(2) -(2x)/(7) +2y`

x = 7

y = 2

Plug in the numbers into the variables

`4(2)^(2) -(2(7))/(7) +2(2)`

4(4) - 2 + 4

16 + 2

18

Your answer is D
