Answer:
169
Step-by-step explanation:
if S(n)=n^2
so,S(13)=13^2
n=13
n^2=13^2
=169
The answer is 3 50 means 3 in this situation
Area of rect. = 5 x 7 = 35
area of triangle = 1/2(2)(7) = 7
area of figure = 35 + 7 = 42

Let's make an equation where x is the number of gallons and y will be the overall price.
2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.
2.5(4)=10
So, the price of 4 gallons is $10.
