Step-by-step explanation:
(5x - 4x)² + 3
(5x - 4x)(5x - 4x) + 3
Simplify.
25x² - 20x² - 20x² + 16x² + 3
Add like terms.
(25x² - 20x²) + (-20x² + 16x²) + 3
Simplify.
5x² - 4x² + 3
Simplify once more.
x² + 3

Answer:
Step-by-step explanation:
The angles x+35 and x+ 40 should equal to the angle supplementary to angle A. You get the equation 2x+75=x+110. You will want to get x alone on one side. First you have to subtract 75 to the right to get 2x=x+35 and then subtract x to the left. You get x=35. Hope this helped!
