Alibrary expansion, begun in 2002, was expected to cost $103 million. by 2006, library officials estimate the cost would be $39 million over budget. by what percent did the actual cost exceed the initial estimate? show the work so i can figure out how to do the question.

initial estimate in 2002 = 103M

Actual cost in 2006 = 142M  (103M + 39M)

% over budget = 39/103 = 37.86%

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 : )
