What is the value of x in the triangle?

x = 40

Step-by-step explanation:

The sum of the angles of a triangle is 180

65+75+x = 180

Combine like terms

140+x= 180

Subtract 140 from each side

140-140+x=180-140

x = 40

x=40

Step-by-step explanation:

The angles inside a triangle must add to 180 degrees, therefore

65+75+x=180

Combine like terms by adding 65 and 75

140+x=180

We want to solve for x. To do this, we need to get x by itself. 140 is being added to x. To undo this, subtract 140 from both sides.

140-140+x=180-40

x=40

(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

i think is g(1)=-1.

hope that i can
