Amechanic billed a customer for 4 hrs. labor plus 215 for parts the total bill was for 375. how much did the mechanic charge for labor per hour?

, i need the equation and the answer

$40

Step-by-step explanation:

Well, since he was charged an extra 215 for parts, we can subtract that from the total bill, 375.

375-215=160.

Now that you only have the amount charged for the 4 hours, 160, you can divide that by 4.

160/4=40.

Now we know that the mechanic charged $40 an hour for his labor.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
