Question

A long one :o.
Myra wants to simplify the following expression.

(2p − 7) + 2(7p + 9)

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

Answer 1

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

last one

Answer 3

explain a lil bit please? :P

Answer 4

lol well (2p-7)+2(7p+9)

first bracket is not multiplied by anything so u can ignore it

so
2p-7+2(7p+9)
now using distributive property
2p-7+ 2(7p)+2(9)
=2p-7+14p+18
=2p+14p+18-7
=16p+11
