Answer:
2( 1.50 + 12.99 + 3.50) = $36.08
Step-by-step explanation:
That is the distributive property way.
You multiply 2 by every number and add them all together.

A(h)=4h+70, A(h)=dollars to rent for h hours, h=hours rented.
B(h)=5h+60, same variable explanations...
....
To compare the two values at 6 hours you have:
A(6)=4(6)+70=24+70=$94
B(6)=5(6)+60=30+60=$90
So at 6 hours Company B would charge $4 less than Company A
...
Savings at 7 hours of rental by using B instead of A is:
S(h)=A(h)-B(h)
S(h)=4h+70-5h-60
S(h)=-h+10
S(7)=-7+10=$3
So at 7 hours, Company B saves you $3.
The hypotenuse is 13.
144 + 25 = 169
Square root of 169 is 13.
