Virty [35]

Answer:

C. 3x^2 + 2x + 1

Step-by-step explanation:

A. 12^2 - (4*3*12) = 0 (there's one solution.)

B. (-3)^2 - (4*3*-18) = 255 (there're 2 real solutions.)

D. 3^2 - (4*0*-3) = 9 (there're 2 real solutions.)

C. 2^2 - (4*3*1) = -18 ✅✅

Keith_Richards [23]

$envo \: car = 65 + 0.10(m)$

$freedom \: ride = 80 + 0.05(m)$

I honestly don't know how to do a)

$envo \: car = 65 + 0.10(250) = 90.00$

$freedom \: ride = 80 + 0.05(250) = 92.50$

He should rent from Envo Car because it would be cheaper.
