Answer:

-3,5

Step-by-step explanation:

d =  \sqrt{(x _{2}  - x _1)  {}^{2} + (y _{2} - y _{1} {} ) {}^{2}  }

5 =  \sqrt{(x - 1) {}^{2} + ( - 1 - 2) {}^{2}  }

5 =  \sqrt{(x - 1) {}^{2} + ( - 3) {}^{2}  }

25 = (x - 1) {}^{2}  + 9

16 = (x - 1) {}^{2}

4 = x - 1

x = 5

Or

- 4 = x - 1

x =  - 3

Answer:

152 square inches

Step-by-step Explanation:

To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)

We should get 80+48+24 which add up to 152.

In case if you are confused which parts you don't understand in these photos, you can ask in the comment.

All really need to do is pick one number. so, we will go with 6 and 87.

6 times 12 is 72 then you subtract that from $87.

That would be 15

To double check, you can use another one. 9 and 123.

9 times 12 is 108. subtract that from 123 and you get 15.

Your answer is B) $15

Hope I helped :)
