Question

WHICH IS HAS THE CORRECT STEPS?

Answer 1

Myra wants to simplify the following expression.

(2p − 7) + 2(7p + 9)

Which option has the correct steps listed out for solving the expression? (6 points)

1) 2p − 7 + 2 + 7p + 2 + 9 using Distributive Property of Addition
2) 2p + 7p – 7 + 2 + 2 + 9 simplifying
3) p (2 + 7) – 7 + 2 + 2 + 9 using Commutative Property of Addition
4) 9p + 6 simplifying

1) 2p − 7 + 2 + 7p + 9 using Distributive Property of Addition
2) 2p + 7p – 7 − 2 + 9 simplifying
3) p (2 + 7) + 0 using Commutative Property of Addition
4) 9p simplifying

1) 2p − 7 + 2 (7p) + 9 using Distributive Property of Addition
2) 2p + 14p −7 + 9 simplifying
3) p (2 + 14) −7 + 9 using Commutative Property of Addition
4) 16p + 2 simplifying

1) 2p − 7 + 2 (7p) + 2 (9) using Distributive Property of Addition
2) 2p + 14p – 7 + 18 using Commutative Property of Addition
3) p (2 + 14) – 7 + 18 using Distributive Property of Addition
4) 16p + 11 simplifying

Answer 2

1) 2p − 7 + 2 (7p) + 2 (9) using Distributive Property of Addition
2) 2p + 14p – 7 + 18 using Commutative Property of Addition
3) p (2 + 14) – 7 + 18 using Distributive Property of Addition
4) 16p + 11 simplifying
