Answer:

x=0

Step-by-step explanation:

If x is 0, then 2x becomes 0. (2.5)^0 would then be 1. 4*1 would give 0 so x=0.

Answer:

14. 2384 in²

15. 291.8 in²

Step-by-step explanation:

14. The total surface area consists of the area of two equal triangles and three rectangles.

The area of each triangle is \frac{1}{2} bh, which is \frac{1}{2}(24)(14)=168 in². The area of both triangles combined is 336 in².

The area of each of the slanted rectangles is base x height, which is 25x32=800 in². The area of both rectangles combined is 1600 in².

The area of the base rectangle is 14x32=448 in².

Therefore, to find the total surface area, you add the area of each side together: 336+1600+448=2384 in².

15. The equation for the surface area of a cylinder is 2\pi r^{2} +2\pi rh.

The radius (r) is 4.6 in and the height (h) is 9.1 in.

Therefore, the surface area is:

2\pi (4.6)+2\pi (4.6)(9.1)=28.888+262.88=291.8\\ in²
