Please Help Quick ASAP Hurry Please Solve these please this is 9th grade pre-algebra Evaluate each expression using the values m=7, r=8 and t=2.
1. 5m-6
2. 4m+t
3. r/t
4. mt

1. 29

2. 30

3. 4

4. 14

Step-by-step explanation:

5*7=35 35-6=29

4*7=28 28+2=30

8/2=4

7*2=14

(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
