When n is 1

5-2n

=5-2*1

=5-2

=3

When n is 2

5-2n

=5-2*2

=5-4

=1

When n is 3

5-2n

=5-2*3

=5-6

=-1

When n is 4

5-2n

=5-2*4

=5-8

=-3

When n is 10

5-2n

=5-2*10

=5-20

=-15

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
