What is the factored form of x2 − x − 20?

(x - 5)(x + 4)

Step-by-step explanation:

x^2 − x − 20

- 20 = -5 * 4

and

- 5 + 4 = -1

So

x^2 − x − 20 = (x - 5)(x + 4)

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
