Several students are cleaning cars. they charge $4 for washing and $4 for vacuuming. both forms of cleaning take the same amount of time. they have time to clean 20 cars. they want to raise a total of $80. how many of each types of cleaning should they do? make a system of equations to show the problem. then solve the problem visually or by making a graph.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

y > 1/3x

y < = -x + 4

hope this : )

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!
