Since it tells you it's a parallelogram you know that opposite sides are parallel. The other piece of information we are given is a pair of consecutive congruent sides. If these sides are congruent the other sides must also be congruent. Letter B is the answer
For this case what we must do is a composition of functions which will be given by: m (x) = 4x - 11 n (x) = x - 10 We have then: m [n (x)] = 4 (x - 10) - 11 Rewriting the function: m [n (x)] = 4x - 40 - 11 m [n (x)] = 4x - 51 Answer: a. m [n (x)] = 4x - 51
