-4 < -12 would be my answer, just from looking at it. If you write it out on a number line, the number -4 is higher than -12. The higher the negative number, the lower it is on the line. So, -4 is greater than -12, not lower than.
133.875
This is the answer because we are given the length and the width of this floor. We are assuming it is a regular rectangle.
So we just multiply the length and the width which is 12.74 x 10.5, which comes out to 133.875
You have the slope and you have two points, so you can use the slope equation to find x.

So your answer is x = 8.
16m cubed - 10m squared......
take out the common factors
they both have a two that can go into it and both have two m's you can take out
so then it becomes
2m squared(8m-5) and thats your answer (:
X can always be used a 1 .
