Answer:
4x + 2y - xy - 8
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × width , that is
A = (x - 2)(4 - y)
Each of the terms in the second factor is multiplied by each of the terms in the first factor, that is
x(4 - y) - 2(4 - y) ← distribute both parenthesis
= 4x - xy - 8 + 2y, thus
A = 4x + 2y - xy - 8
Answer: 4x - xy - 8 + 2y
Step-by-step explanation:
(x-2)(4-y) = 4x - xy - 8 + 2y
