7. sylvia made a poster shaped like the triangle shown below. (1 point)
26 in.

what is the length of the third side of the triangle?

10
12 in.
14 in.
16 in.

 10 inches.

Step-by-step explanation:

Use the Pythagorean Theorem . c² = a² + b²

to find a², subtract b² from both sides

c² - b² = a²

26² - 24² = 10²

676 - 576 = 100

√100 = 10

(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
