What is half 7minutes and 24 seconds

3 minutes and 42 seconds

Step-by-step explanation:

So I would convert that minute into seconds

7*60=420

So 420+24=444

Divide by 2

444/2=222

Now divide by 60 to convert it back to minutes

222/60= 3.7

3.7 minutes or

7/10*60=42

3 minutes and 42 seconds

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
