Amanda filled her gas tank three times last week. Here are the amounts of gas she bought (in gallons). 10.7,15 , 3.7 What is the total amount of gas Amanda bought last week?

29.4 gallons

Step-by-step explanation:

Given that

the amounts of gas she bought (in gallons). 10.7,15 , 3.7

total amount of gas Amanda bought last week will be sum of 10.7 , 15 and 3.7

total amount of gas Amanda bought last week = 10.7 + 15 + 3.7

=>  total amount of gas Amanda bought last week = 29.4

Thus, Amanda bought 29.4 gallons in total in last week.

(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
