x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9

Answer:
See below
Step-by-step explanation:
To begin, it is volume, not area
1. 8 x 12 x 17 = 1632 in ^3
5. 9 x 9 x 13.5 = 1093.5 in^3
If you want to find SURFACE AREA:
1. 2(8 x 12) + 2(8 x 17) + 2(17 x 12) = 872 in^2
5. 2(9 x 9) + 4(9 x 17) = 774 in^2
The answer is 8n2 + 26n + 6
