Jim has a total of 77 red and blue marbles. the number of blue marbles is five more than twice the number of red marbles.

Let r and b represent, respectively, the number of red and blue marbles. We know a couple of things:

So, we have the following system:

The second equation gives a way to express b in terms of r. Use this expression in the first equation:

So, if Jim has 24 red marbles, he has blue marbles.

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
