How much wood needed (i.e. the surface area)
The question is incomplete, as the net of the triangular prism is not given. So, I will answer with the attached net.
To calculate the surface area, we simply calculate the area of each face of the net.
The area of the net is as follows:
Area= 2 * Area of Triangle + 2 * Area of 2 Congruent Rectangles + Area of the third rectangle
So, we have:
Your answer would be C
24
x = 24
1.) put the equations together and equal them to 180
2x + 4 + 6x - 16 = 180
2.) combine like terms
8x - 12 = 180
3.) divide both sides by 8
8x = 192
4.) simplify
b=-1
3(b+2)+2(b-3)=-5
3b+6+2b-6=-5
5b=-5
