Answer:
use the distance Formula D=sqrt of {(x1-x2)^2+(y1-y2)^2}
Step-by-step explanation:
So(-5--9)^2 + (-5- -2)^2 =
(4)^2 + (-3)^2 =
16 + 9 = 25
and the square root of 25 is 5.
5 is the answer

Answer:
Here is a way one of my math teachers taught me.
For + x + = +:
In elementary school, you were taught by your math teacher that an positive number multiplied with a positive number is equal to a positive number. To solve, use basic rules of multiplications.
For + x - = -:
Think of it this way. There are two line segments that makes a positive sign. When multiplying, you are subtracting a line, which would result in a negative sign. Whenever a positive multiplies a negative, it is always a negative outcome.
For - x - = +:
There are two lines given (two negatives). When multiplied, the two lines make a positive sign (which is made by drawing two lines). This shows that two negative numbers multiplied or divided together will make a positive sign .

The first thing is that you cant negative a negative number. 7h=-2h+18.
then then you add 2h to both sides. you get 9h=18
then you divide both sides by 9. you get h=2.
I hope I helped.
