Question

Plz help I am giving away 20 points!!!!!!!!

Answer 1

Okay, so on number one I have no idea. I keep getting 20 because 14 - (-3)2 = 14- (-6) which is really 14 + 6=20.

Number 2 is r+15=61

Number 3 I didn't get any of those answers because you have to solve what is in the parenthesis first so3*5= 15+1=16 then you multiply that by two giving you 16*2=32 and 42-32=10

Answer 2

Hi!

1. The answer is D because -3 squared is 9 (it's positive because a negative times a negative equals a positive) and 14 - 9 = 5.

2. Just use common sense for this one. According to the question, 15 is LESS than 61 and r and 15 add up to get 61. Therefore, the answer will be r + 15 = 61.

3. I'm honestly not sure for this one. Doing the calculations I got 10, but there isn't a choice for that. Are you sure you copied the answers correctly?

Hope that helps! Piece of advice: problems like this are easy when you go through it slowly and use common sense. Maybe try them on your own next time? :)
