X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
8×5×12in^2+8×5×10in^2+12×10in^2=480 in^2+400in^2+120in^2=1000in^2 if one takes all the angles
If not then the answer would be 420in^2+120in^2=540in^2

Answer:
![-6-7\left(c+10\right)=-7c-76](https://tex.z-dn.net/?f=-6-7%5Cleft%28c%2B10%5Cright%29%3D-7c-76)
Step-by-step explanation:
Given the expression
![-6\:-\:7\:\left(c+10\right)](https://tex.z-dn.net/?f=-6%5C%3A-%5C%3A7%5C%3A%5Cleft%28c%2B10%5Cright%29)
simplifying the expression
![-6-7\left(c+10\right)](https://tex.z-dn.net/?f=-6-7%5Cleft%28c%2B10%5Cright%29)
Expanding -7(c + 10) = -7c - 70
![-6\:-\:7\:\left(c+10\right)=-6-7c-70](https://tex.z-dn.net/?f=-6%5C%3A-%5C%3A7%5C%3A%5Cleft%28c%2B10%5Cright%29%3D-6-7c-70)
subtract the numbers: -6 - 70 = -76
![=-7c-76](https://tex.z-dn.net/?f=%3D-7c-76)
Therefore, we conclude that:
![-6-7\left(c+10\right)=-7c-76](https://tex.z-dn.net/?f=-6-7%5Cleft%28c%2B10%5Cright%29%3D-7c-76)
