7/3 + 3 (2/3 - 1/3)^2

20/9

Step-by-step explanation:

Not sure what you need, but here is that simplified as much as possible:

(given) 7/3 + 3 (2/3 - 1/3)^2

(subtract) 7/3 + 3 (1/3)^2

(square) 7/3 + 3 (1/9)

(mixed number to improper fraction) 7/3 + 38/9

(changing 7/3 into 1/9s) 7/3 = 21/9

(expression) 21/9 + 38/9

(adding) 40/9

(simplify) 20/9

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
