Question

Fatima wants to simplify the following expression.

7(p + 3) + 2(p – 1)

Which option has the correct steps listed out for simplifying the expression?

Answer 1

1) 7 (p) + 7 (3) + 2 (p) + 2 (−1) using distributive property of addition
2) 7p + 21 + 2p −2 simplifying
3) 7p + 2p + 21 – 2 using commutative property of addition
4) p (7 + 2) + 21 – 2 using distributive property of addition
5) 9p + 19 simplifying

1) 7 (p) + 7 (3) + 2 (p) + 2 (−1) using distributive property of addition
2) 7p + 21 + 2p −2 simplifying
3) 7p + 2 + 21 – 2 using commutative property of addition
4) 7p + 21 + 2 −2 using associative property of addition
5) 7p + 21 simplifying

1) 7 + p + 7 + 3 + 2 + p + 2 + (−1) using distributive property of addition
2) p + p + 7 + 7 + 3 + 2 + 2 − 1 using commutative property of addition
3) p (1+1) + 7 + 7 + 3 + 2 + 2 − 1 using distributive property of addition
4) 2p + 20 simplifying

1) 7p + 3 + 2p −1 using distributive property of addition
2) 7p + 2p + 3 − 1 using commutative property of addition
3) 7p + 2 + 3 – 1 using associative property of addition
4) 7p + 4 simplifying
