Show your work pleasejohn wants to know the square footage of his living room in order to lay new hardwood floors. The living room has vertices at the coordinates (1,5) (11,3) (3,15) (13,13). If each unit one the coordinate plane is one square unit, then how many square feet of flooring must john buy in order to cover his entire living room?

extension questions:
1) john wants to buy 10% more flooring than his room requires to account for errors. If boxes of flooring cover 20 square feet, how many boxes will john need in order to account for errors in measurement?
2) if hardwood flooring costs $3.98 per square foot, what will it cost john to put new floors in his living room?

Answers

Answer 1

Answer: 1) would be 2 boxes because the room is 25 ft²
2) $99.50 if you do 25 x 3.98, or if they want 40 x 3.98 it would be $159.20

what is the solution ?

Answers

Answer: (4.5, 6.5) is your solution

Step-by-step explanation:

You need either the x term or the y term to be the same in both equations so you can eliminate them...

8x=2y+5

6x=2y+14

Now you can subtract the two equations...

2x=9

Divide 9 by 2....

x=4.5 or 4 1/2

Plug in x into one of the original equations to find y...

13.5=y+7

Subtract 7 from 13.5...

6.5=y

How much water was in the pool orgininally?

Answers

To find how much water was in the pool originally, you need to write the function for how fast the water is leaving the pool.

Your function is

y=-8x+b

y is amount of water in the pool

x is how many hours

b is the original amount

Since you know y and x, plug those into the function.

132=-8(6)+b

132=-48+b

b=180

The original amount of water in the pool was 180 gallons.

I didn't mean to reanswer the question, I'm sorry! I didn't see that there was already an answer when I began answering.

-8 gallons/ hour
6 hours
-8 × 6 = -48

132 + 48 = 180 gallons
