I believe the answer is 3. Im not sure so sorry if you get it wrong
Number of times she climbed 5-mile mountain trail = x
Number of times she climbed 10-mile trail = y
total distance of the 5-mile mountain trail will be = 5*x =5x
total distance of the 10-mile mountain trail will be = 10*y = 10y
equation that can be used to find the number of times she hiked each trail is therefore
5x + 10y = 90
Answer:
A
Step-by-step explanation:
you will get 3(x-1)×(x+1) you can get the 3 and x by itself then it would be x+3
