Anumber n is 25% of some number a and 35% of a number b. a> b, a

n*25/100 = a

25n = 100a 1st eqn

a*35/100 =

35a = 100b

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
