Answer:
Step-by-step explanation:
The slope of a line between two points can be calculated by dividing the difference of y values by the difference of x values
in this case

X=60degrees
bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.
Hope this helps.

Answer: (x+4) (x+2)
Step-by-step explanation:
x^2 + 2x + 4x +8
4 times because if you count 10, 20, 30, 40, so it has to be 4
