Question

simplify the expression 4(x + 3) - 2(x - 2).
a. 2x + 16
b. 2x - 8
c. 2x - 10
d. 2x + 10
simplify: a² + 3a²
a. 3a²
b. 4a
c. 4a²
d. a³

Explanation:

First Expression Step1: Expand the terms

\(4(x + 3) - 2(x - 2) = 4x + 12 - 2x + 4\)

First Expression Step2: Combine like terms

\((4x - 2x) + (12 + 4) = 2x + 10\)

Second Expression Step1: Combine like terms

\(a^2 + 3a^2 = (1 + 3)a^2 = 4a^2\)

Answer:

d. \(2x + 10\)
c. \(4a^2\)
