Question

2. Use the distributive property to evaluate the expression.

A) 4(x-2)
B) 3(y+9)
C) -2(3-r)

Answer 1

a) 4x-8

b) 3y + 27

c) -6 + 2r

Explanation:

Here, we want to use the distributive property to evaluate the given expressions

Mathematically, the distributive property is;

(a + b) * c = (a * c) + (b * c)

So we use this on each of our questions;

a) 4(x-2)

= (4 * x) - (4 * 2) = 4x-8

b) 3(y + 9)

= (3 * y) + (3 * 9)

= 3y + 27

c) -2(3-r)

= (-2 * 3) - (-2 * r)

= -6 + 2r
