They are opposites of each other.
-13.2 + 8.1 = -5.1
13.2 - 8.1 = 5.1
It would be A. <span>y = −2x − 4.
Hope this helps!!

Answer:
Step-by-step explanation:
<u>STU is an equilateral triangle. And:</u>
- ST = 2x - 1
- SU = 5x - 37
- TU = x + 11
<u>All sides are equal. Then take one pair and solve for x:</u>
- 2x - 1 = 5x - 37
- 3x = 36
- x = 12
<u>Substitute x to find the side length:</u>
- 2x - 1 = 5x - 37 = x + 11 = 23
