Answer:

(2x - 1) (x - 7).

Step-by-step explanation:

2x^2 - 15x + 7

Use the ac method:

ac = 2 * + 7 =  +14

-1 * -14 =  + 14 and -1 + -14 = -15 so we replace -15x by - x - 14x:

2x^2 - x - 14x  + 7

= x(2x - 1) - 7(2x - 1)

= (2x - 1) (x - 7)

Bill wants to rent a car. Rental Company A charges $35 per day plus $0.10 per mile driven. Rental Company B charges $25 per day
vova2212 [387]

After 300 miles.

35+0.1x= 25+0.15x

<u> -0.1x -.01x</u> (0.1- 0.1 crosses out)

35= 25+0.15x

<u> -25 -25 </u> (25- 25 crosses out)

15= 0.15x

15/0.15= 0.15x/0.15 (crosses out)

300= x
