What is the perimeter of this rectangle? w2 + 13
W + 5
A w3 + 18
B 2W + 2w + 36
o w3 + 5w? + 13w + 65
D w
+ W + 18
DA
(ОВ

B. 2w^2 + 2w + 36

Step-by-step explanation:

The equation to find the perimeter of anything is: Length + Length + Width + Width = Perimeter.

Applying this logic to this problem, the equation would be as follows:

Then, we simplify. The like terms go together, and you have your solution.

Let x represent the number of GB of data used per  month .Let f(x)  be the function that represents the total cost .

A) For Company A it is given :Company A offers unlimited minutes and texts for a flat fee of $50 per month and charges $1.50 for each GB of data used per month. Charge for x GB data used = 1.50x.

Total cost f(x)= 1.50x+50

B) Given :Company B offers unlimited minutes and texts for a flat fee of $35 per month and charges $5.00 for each GB of data used per month.Cost of x GB data = 5x

Total cost f(x)=5x+35.
