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

a

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
