5 is A, because it's the only number that is whole when square rooted.
6 is confusing because it only gives you one number per answer, unless you are to add the two distances together? Then it would be 7 because X's distance is +4 and Y's distance is +3
I do not have an answer for 7
8 is 3.7 (or C)
9 is an easy one. Find out what the L and W is, and since it's a square we only need to find one of them. We square root the area and we are given 14.96662955, if rounded we get 15. So the answer is A
10 I don't understand the "estimate" for a square root number, I was not taught that.
For this case we have the following polynomial:

What we must do for this case is to factor the polynomial, so that we have:
1) The number of bottles
2) the weight of each bottle.
We have then:

Answer:
A factorization that could represent the number of water bottles and weight of each water bottle is:

Answer:
<h2>2</h2>
Step-by-step explanation:
Follow PEDMAS

Follow rule : -(-a)= + a

The equation would be y=2/3x+300
