Sam must inspect 11/14 of a mile of high voltage line. he has already inspected 3/14 of a mile. how much additional line must he inspect?

Hey!

Sam has to inspect a total of 11/14 of a mile. He has already inspected 3/14 of a mile. Subtract the amount he has to inspect by how much he already has done.

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

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 : )
