the water usage at a car wash is modeled by the equation w(x) = 5x3 + 9x2 − 14x + 9, where w is the amount of water in cubic feet and x is the number of hours the car wash is open. the owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. the amount of decrease in water used is modeled by d(x) = x3 + 2x2 + 15, where d is the amount of water in cubic feet and x is time in hours.
write a function, c(x), to model the water used by the car wash on a shorter day.
c(x) = 5x3 + 7x2 − 14x − 6
c(x) = 4x3 + 7x2 − 14x + 6
c(x) = 4x3 + 7x2 − 14x − 6
c(x) = 5x3 + 7x2 − 14x + 6

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

what

d. corresponding side lengths in similar triangles are proportional in length.
