F(x) = (x - 3)(x - 7)
expanding the brackets gives:
f(x) = x^2 - 10x + 21
Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.
Add like terms to get 5x - 20 = 180
5x = 200
x = 40
Answer:

Step-by-step explanation:
Let d represent the number of pizza delivery days.
We have been given that a pizza delivery worker drives the motor scooter only on days he is working, during which he drives an average of 50 miles per day. So the number of miles driven in d days will be 50d.
As the delivery worker purchased a used motor scooter that had been driven 12,100 miles. This means that initial value or y-intercept will be 12,100.

Upon substituting our given values we will get,

Therefore, the equation
models the total number of miles driven in d days of pizza delivery.
He drove 260 miles. Hope this helps
