What is twice a number plus 4 is less then 12

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
