The answer to this is
3(x+1)(x+8)
7x-3 would then be 7(-2) -3. 7 multiplied by -2 would be -14. -14-3= -17
hope this helps
Answer: the slope is 2/1 or 2
Step-by-step explanation: slope is written rise over run, meaning y/x. By finding the difference between 13/5 and 17/7, then 17/7 and 21/9 to confirm, you can see that the difference is 4/2, which reduces to 2/1, which is simplified to 2.
