Calculate the area, in terms of x and in simplest form, of the rectangle shown below. 5x + 4
2x - 5

5x +4 the x is 2 the answer to this is 14

2x-5 the x is 4 the answer to this is 13

(a) the volume of the cone is 20/3 in3

hence, option a is 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.
