The base of this right prism is an isosceles triangle. what is the surface area of the prism?

256 square feet

Step-by-step explanation:

To find the surface area, find the area of each surface of the prism.

The triangles are A = 1/2bh. Substitute b = 12 and h = 8.

A = 1/2*12*8 = 48

Together the two triangle face is 96 square feet.

The prism also has two identical prism surfaces whose ares are found using A =b*h. Substitute b = 5 and h = 10. A = 5*10 = 50. The two faces together are 100.

The last surface face of the prism has area with b = 5 and h = 12. The area is A = 5*12 = 60.

The surface area of the entire prism is 96 + 100 + 60 = 256.

The correct answer is C

Step-by-step explanation:

I took the test and its correct

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
