The area of a rectangle is 15+5y square feet. which of the following expressions could be the length of the sides of the rectangle, in feet a. 5 and 3y b. 5 and 3+y c. 5 and 5+y d. 3 and 5+3y

B. 5ft and (3 + y)ft

Step-by-step explanation:

Area of a rectangle = 15 + 5y

Possible sides of the rectangle would measure 5ft and (3 + y)ft

Because: 5ft × (3 + y)ft = 15 + 5y ft

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

d is correct
