Question

2. If Sam runs around an octagonal trail. He ran a total of 80m. What is the distance
of one side of the trail?

Answer 1

Answer:

Let f(x) = 3x² - x³ - 3x + 5 and g(x) = x - 1 - x²

Long Division Method:

-x² + x - 1) -x³ + 3x² - 3x + 5(x - 2

               -x³ +  x²  - x

                -------------------------

                          2x² -  2x  +  5

                          2x²  -  2x  +  2

                           ----------------------

                                              3

     

Verification:

Dividend = Divisor * Quotient + Remainder

               = (-x² + x - 1) - (x - 2) + 3

               = -x³ + x² - x +  2x² - 2x + 2 + 3

               = 3x² - x³ - 3x + 5

Step-by-step explanation:

Answer 2

Total distance = 80

The shape/area run around it = octagonal

Distance of one side = Distance/8

=80/8

=10

One side of octagonal = 10
