The length is 9.
The formula to find the perimeter of a rectangle is
2L + 2W = P.
2L + 2(4) = 26.
2L + 8 = 26.
2L + 8 (-8) = 26 (-8).
2L = 18.
2L/2 = 18/2.
L = 9.
Answer
A. 16.5
Step-by-step explanation:
First you calculate what 45% of 30 is. Then you subtract that from 30.
I can help with 17-20:)
Slope = m = y2 - y1/ x2 -x1
So, you have already found the y1 and y2 and x1 and x2.
So, plug the numbers into the equation:
3 - 1/(-5) - (-2)
4 - (-3)/(-1) - 1
(-5) - 5/2 - 4
2 - (-1)/(-1) - 1
Then solve.
(Btw, the formula looks like this:

Hope this helps!!!
Answer:
x = -10
Step-by-step explanation:
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
