The sides of a triangle measure 2.24 inches, 3.56 inches, and 4.50 inches. what is the perimeter of this triangle? report the answer with the appropriate number of significant digits.

perimeter of the triangle is 10.3 inches.

Step-by-step explanation:

Perimeter of any triangle = sum of all three sides of the triangle.

In this question sides are 2.24 inches 3.56 inch and 4.5 inches.

So perimeter of the given triangle = 2.24 + 3.56 + 4.5

                                                        =  10.3 inches

Therefore, perimeter of the triangle is 10.3 inches.

(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
