Okay so first subtract 9x^2-10x+1 which gives you (9x -1)(x-1). then do the same to the next one which gives you -2(x^2 -2x +5) when you subtract you should get 11x^2 - 14x +11
Okay do 4*10 and 7*10 (you get 40/70) and then do 3*7 and 10*7 (so now you've got 21/70) then add 21/70+40/70 and that's the total distance
Answer: 15%
Step-by-step explanation:
They gave their server $8.79 and their total bill was $58.60.
The question wants to know how much percentage of the total bill the tip they gave is:
= Tip / Total bill * 100%
= 8.79 / 58.60 * 100%
= 15%
