Please help me answer these!!

Step-by-step explanation:

Line WQ could also be called Line QW (These are uppercase letters, two points that are on the line and should have a line symbol across the top of them) and also lines are often named with a single small letter, in this case, Line g.

You can name a plane by using three non collinear points on the plane with a little ane symbol in front (looks kind of like a parallelogram) *planesymbol* RST

(or RQT or SQT)

R, Q, and S are collinear (all on the same line) and T (or W) is a fourth point that is not on the same line as the other three points.

W is off the plane that R, S, and T are in.

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
