Answer:
249.6
Step-by-step explanation:
width x height x 1/2 = area fo a triangle
12(2) x 10.4(2) x 1/2 = 249.6
I assumed this means all of the surface area. Hope this helps. Sorry if I'm wrong.
The answer should be 37
2(x+8) = 3(x-7)
distribute
2x+16 = 3x-21
Subtract 2x from both sides
2x+16-2x = 3x-21-2x
16 = x-21
Add 21 to both sides
16+21 = x-21+21
