Adriana rode the Finding Nemo Submarine Voyage at Disneyland. The submarine traveled to 20 feet below sea level, then ascended 23 feet. What elevation is Adriana at now?

3 feet

Step-by-step explanation:

so if she started at 0 feet, then descended 20 feet, she would be at -20 feet, then ascended 23 feet, she would then be at 3

0 - 20 = -20

-20 + 23 = 3

(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

the answer is: the length is 5/6 yards.
