If k(x) = 5x – 6, which expression is equivalent to (k + k)(4)?

Iwant to know what 3g+5h+4g-2h is my teacher is too selfish to tell us

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

Use the distance formula to find the distance between (-3,5) and (3,1)
