Please help!! Suppose you drive a car 192 miles on one tank of gas. The tank holds 16 gallons of gas. (Assume the car travels the same distance for each one gallon of gas)

The number of miles traveled varies directly with the number of gallons of gas you use.
a. Write an equation that relates miles tracked to gallons of gas used.
b. How far can you travel with 3.7 gallons of gas? (Make sure to show the calculations you did to determine this answer)

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.

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
