The shadow cast by an object on a sunny day is directly proportional to the height of the object. If a person 66 inches tall casts a shadow 67 inches long, how tall is a tree which casts a shadow 42 feet in length? Round to the nearest hundredth if necessary.

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
