Simplify the expression below: 3(4x + 2y)

• 12x+6y

• 12x+2y

• 12y+6x

• 34x+32y

Simplify the expression below: 4(4y - 3x)

• 16y-12x

• 16x-12y

• 16y-3x

• 4y-12x

Combine like terms: 4f + 3e - 2f + 2e

• 2f+2e

• 4f-2f+3e+2e

• 6f+5e

• 5f+2e

which is the equivalent to expression:

2(x + 2y) - 3y

• 2x+y

• 6x-2y

• y

• 2x+4y-6y
