Simplify this expression by distributive property and combining like terms. 8c + 9 (c + 2)

17c + 18

Step-by-step explanation:

Distributive property: a(b + c) =a*b +a*c

8c + 9(c +2) = 8c + 9*c + 9*2    {Distributive property}

                    = 8c + 9c + 18  

Combine like terms, her 8c & 9c are like terms

                      = 17c + 18

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
