12x + 2 (3x - 7) - 8 show your work

18x - 22

Step-by-step explanation:

12x + 2 (3x - 7) - 8

underlined section is indicating that you need to multipy

so 2 mulitiplied by 3x is 6x

and  2 multiplied by 7 is 14

your new expression should look like this:  12x + (6x -14) - 8

now to simplify the expression you combine like terms, so combine the integers, and combine the X numbers.

so 12x and 6x = 18x

and (-14) and (-8) comes out to (-22)

this is the final

18x - 22

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5
