A car manufacturer was having a sale on cars. Each car was being sold for 4,000 dollars less than the original price. 30 cars were sold every ¼ of an hour. At this rate, how many cars would be sold in an hour?

120

Step-by-step explanation:

1/4 of an hour is 15 minutes so 4 15 minutes=1 hour so 30 cars times 4 15 minutes= 120 cars in an hour

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
