The relationship between mary’s age (m) and john’s age (j) can be represented by the equation: m = j + 4

Step-by-step explanation:

Given equation: M = J + 4; or its equivalent J = M - 4

M = 5, J = 5 - 4 = 1

M = 8, J = 8 - 4 = 4

J = 12, M = 12 + 4 = 16

M = 15, J = 15 - 4 = 11

J = 20, M = 20 + 4 = 24

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
