Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{14x + 4}}}}}$

Step-by-step explanation:

$\sf{(5x + 2) - ( - 9x - 2)}$

When there is a ( - ) sign in front of an parentheses in an expression , change the sign of each term in the expression. Also, remove the parentheses

$\dashrightarrow{ \sf{5x + 2 + 9x + 2}}$

Collect like terms

$\dashrightarrow{ \sf{14x + 2 + 2}}$

Add the numbers : 2 and 2

$\dashrightarrow{ \sf{14x + 4}}$

Hope I helped!

Best regards! :D

For a school picnic, leslie ordered a box of fresh-baked gingerbread cookies and sugar cookies. She got 60 cookies in all. 15 of

OlgaM077 [116]

Answer:

Pretty sure 25%.

Step-by-step explanation:

First, you would need to see how many times 60 goes into 100, because a percent is ALWAYS over 100. You should get an answer of 1.66666667. Then you if you multiply it to one of the numbers then you have to do it to the other number. So, you would do 15 times 1.66666667. You would get 25. So, that would be 25 over 100 or 25/100. And 25 over 100 is 25%.

I hope I helped! :) Sorry if it's wrong :(
