mia drove her car at a rate of 60 mph from her home to los angeles. her mother, katrina, made the same trip at a rate of 80 mph,

Ad libitum [116K]

So if Katrina did 80mph and

Mia did 60mph

Lets say the destination is 90 miles away that would take 1hr 30minsfor Mia and

1hr 10mins for Katrina. so that's only a gap of 20minutes not half an hour.

So if the destination was 120miles away it would take Mia 2 hours and Katrina 1hour 30mins that is a gap of 30mins.

ANSWER: 120miles

slamgirl [31]

$A=lw \Rightarrow l=\frac{A}{w}$
A - area, l - length, w - width

$w=x-2 \\
A=x^3-2x-4 \\ \\
l=\frac{x^3-2x-4}{x-2}=\frac{x^3-2x^2+2x^2-4x+2x-4}{x-2}=\frac{x^2(x-2)+2x(x-2)+2(x-2)}{x-2}= \\
=\frac{(x^2+2x+2)(x-2)}{x-2}=x^2+2x+2$

The answer is D. x²+2x+2.
