Answer:
2(x-5)(x+4)
Step-by-step explanation:
2x^2 − 2x − 40
Factor out a 2
2(x^2 -x -20)
What 2 numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
2(x-5)(x+4)
15.5:1
62/4 = 15.5
15.5 : 1
It is most likely positive.
You have to use the Pythagorean theorem because it is a right triangle. Consequently it is the square root of 12 squared plus 17 squared or approximately 20.81
