3(2x + 12) = -2(x - 4) + x

-4

Step-by-step explanation:

1. Use the distributive property to get 6x + 36 = -2x + 8 + x

2. Combine like terms 6x + 36 = -x + 8

3. Subtract 36 on both sides. 7x + 36 = 8 > 7x = -28

4. Divide by 7

-28/7 = -4  x=4

x = -4

Step-by-step explanation:

3(2x + 12) = -2(x - 4) + x

6x + 36 = -2x + 8 + x

+2x          +2x

8x + 36 = 8 + x

-x                  -x

7x + 36 = 8

     -36    -36

7x = -28

7x/ 7  = -28/ 7

x = -4

i got 142 as my answer

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
