Fulton is building a doghouse he cuts 5 equal sized pieces from a board that is 15 ft long after cutting the pieces he has 2 and 1/2 feet of wood left which of these equations and expressions will when solver simplified give the length of the five pieces of wood Folsom cut

i know the answer is 3

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 : )

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
