From my research the answer for this question is 5
Step-by-step explanation:

3(x2+2x-3)-4(4x2-7x+5)
3x2 + 6x - 9 - 16x2 + 28x - 20
-13x2 + 34x - 29
1. Take away the parentheses. x+2x+40+3x-50=15002
2. Add the X’s together.
x+2x+3x= 6x —> 6x+40-50=15002
3. Subtract 50 from 40.
40-50= -10 —> 6x-10=15002
4. Move -10 to the right hand side to make it positive.
6x=15002+10
5. Add 15002 and 10 together.
6x=15012
6. Divide 15012 by 6. Which makes the answer X=2502
the length of a side of a square is the square root of the area
side length = sqrt(164)
side length = 12.8062
Round the answer as needed
since it asks for approximate, it is probably going to be 13 inches
