Okay so if the area is 324 square inches and one of the sides is 12 inches, then you would have to divide the area by the width. so, for your length you would get 27. to find the perimeter, you would add all of the sides together (12+12+27+27) and you would get 78 inches.
AC = 3x - 1
AB = 4 x + 8
LINE: A—C—B
4x + 8 is the equation for the whole line, including BC. So you would just have to subtract 3x - 1, the equation for AC, from the equation for AB to find the equation for BC: 4x + 8
-3x - 1
So BC would equal x + 9, since the negative turns the “- 1” into a positive one.

Step-by-step explanation:
-x, -(x+1)
-x-(x+1)=10506
x^2+x-10506=0
Answer:
you have to round up so it would round up to 35.800
