Solve: 2sec(x) + 5 = 9 which are solutions of the given equation?

The equation is equivalent to the given equation is cos(x) = 1/2

For the second question, the solution s of the given equation are π/3 + 2kπ and 5π/3 + 2kπ

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 : )
