Addison drove 265 miles in 10 hours. On average, how fast did she drive in miles per hour?

Work Shown:

distance = rate*time

d = r*t

265 = r*10

265/10 = r

26.5 = r

r = 26.5

=4x^2 +  3/2 x − 7

Step-by-step explanation:

Let's simplify step-by-step.

x /2  −3 + 4x^2 + x − 4  

=  1 /2 x + −3 + 4x^2 + x + −4

Combine Like Terms:

=  1 /2 x + −3 + 4x^2 +x + −4

= (4x^2) + (  1 /2 x + x) + ( −3+−4 )

= 4x^2 + 3 /2 x + −7
