Question

Distribute and simplify: 7(2x-4) + 2(3x+1)

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

$4y^{2} -\frac{2x}{7} +2y$

x = 7

y = 2

Plug in the numbers into the variables

$4(2)^{2} -\frac{2(7)}{7} +2(2)$

4(4) - 2 + 4

16 + 2

18

Your answer is D
