Rewrite it in the form a^2 - 2ab + b^2, where a = d and b = 2
d^2 - 2(d)(2) + 2^2
Use the Square of Difference: (a - b)^2 = a^2 - 2ab + b^2
(d - 2)^2

Answer:
below.
Step-by-step explanation:
x is the number of weeks
a) Ms. Smith = 14 + 4x
Mr Smith = 20 + 2x
b) 14 + 4x = 20 + 2x
4x - 2x = 20 - 14
2x = 6
x =3
three weeks
c)
Ms. Smith = 14 + 4x = 14 + 4(3) = 26
Mr Smith = 20 + 2x = 20 + 2(3) = 26
