Which term contains a coefficient?
m + 3n + p + 3

Step-by-step explanation:

A coefficient is a number  (integer) which is multiplied with an unknown value (the variable of a single term or the terms of a polynomial).

In this case , n is the variable of a single term and 3 is the coefficient.

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
