PLEASE HELPP ME I WILL GIVE THIS PROBLEM IS WORTH 20 POINTS. PLEASE GIVE RIGHT ANSWER.

36 inches/second = yards/minute how many yards?

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

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36
