3(x-7)+8=-20
Multiply the bracket by 3
(3)(x)(3(-7)+8= -20
3x-21+8= -20
3x-13= -20
Move -13 to the other side. Sign changes from -13 to +13.
3x-13+13= -20+13
3x= -7
Divide by 3
3x/3= -7/3
x= -7/3 or in mixed number : -2 1/3
Answer : x= -7/3 or in mixed number : -2 1/3

The answer:
<span>according to the question the length is its width, that means
w=l
</span><span>She wants to enlarge the picture to have an area of 192 in2,
that means Area = </span>wxl = 192 in²
so, since w=l, we can write that Area = wxl =w²=l²= 192 in², this implies:
w=sqrt (192) = 13.85 in
finally the width w = 13.85, and the length l= 13.85 because w=l
