If car #1 gets 43.2 miles per gallon and car #2 gets 35.9 miles per gallon. calculate the difference in costs if you drive a distance of 300 miles with each car, if gasoline is $3.19 per gallon?

Hey!

Hope this helps...

Car #1: 300/43.2 = 6.9444 gallons

(Rounded) Car #2: 300/35.9 = 8.3565 gallons

(Rounded) Car #1: 6.9444*3.19 = $22.16 to re-fill their tank

(Rounded) Car #2: 8.3565*3.19 = $26.66 to re-fill their tank

(Rounded) Difference: $26.66 - 22.15 = $4.50

To re-fill Car 2's tank is approximately $4.50 more to re-fill Car 1's tank...

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
