Angle 7 and angle 8 are complementary. angle 5 equals angle 8 and angle 6=29. ​

What are “like terms”? why can we only add like terms?

With both problems. a.s.a.p directions on photo ^

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
