Find the value of x
help please

120

Step-by-step explanation:

Could be wrong but, I think the 40 degrees is equivilent to the angle right below the x, been a while since geometry so forgot what theory or law it's called. But anywas there's a straight line which equals 180 degrees. So 180-40-20 is 120... I dont know if this is right but I feel like it would be the only way to solve it...

120 degrees I think

Step-by-step explanation:

Since the 40 degrees correlates, the line has a value of 20 degrees and 40 degrees making 60 degrees... a straight line is always 180 degrees so 180-60= 120degrees I am pretty sure

(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
