Karl set out to alaska on his truck. the amount of fuel remaining in the truck's tank (in liters) as a function of distance driven (in kilometers) is graphed. how much fuel did the truck consume every 100 kilometers?

11

step-by-step explanation:

32.50-7.50=25

225/25=11

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

if it's asking for the proper expression then it could be 8x= .8 each person would get a .1   portion of the turkey
