Shannon has already cycled 9 kilometers this year, plus she plans to cycle 1 kilometer during each trip to work. How many trips
1 answer:
Answer:
Shannon has to make 41 trips to cycle a total of 50 kilometers.
Step-by-step explanation:
Given that
Shannon has cycled 9 kilometers this year
Let x be the number of trips that Shannon will make during the year
As she cycles 1km per trip, the total distance in trips will be: 1x
She has to cycle 50 kilometers in a year so the equation for this problem is:
Solving this equation will give us the number of trips she has to make
Hence,
Shannon has to make 41 trips to cycle a total of 50 kilometers.

Answer:
A) (x +2)(x -3)² = 0
Step-by-step explanation:
Synthetic division by (x-3) gives the quadratic x² -x -6, which has factors (x -3) and (x +2). This is confirmed by another round of synthetic division.
The resulting factorization is ...
... (x +2)(x -3)² = 0
