Show that (2, 1) is a solution of the system of equations.

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 : )

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

it has the same slope and a different y-intercept

hope this : )
