Hard word problem Solve the following word problems using positive and negative numbers.

Find the difference in height between the top of a hill 973 feet high and a crack caused by an earthquake 79 feet below sea level.

As top of hill means a positive value so, 973 feet.

As crack means below or lower, it has negative value so, -73 feet.

As we know that Difference means the subtraction of two numbers, so,

Therefore, the difference in height between the top of a hill 973 feet high and a crack caused by an earthquake 79 feet below sea level is 1052 feet.

step-by-step explanation:

(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
