1) Cancel out the common factor which in this case is 8 
2)First apply exponent rule 
now cancel out the common factors which are n and n+7 leaving you with 
3)Factorize 
cancel out the common factor in this case x+2 leaving you with 
4) Factorize 
cancel out the common factor in this case 3w-1 leaving you with 
5) In the picture
6)In the picture
I am REALLY tired sorry I wont be able to do the rest, I hope these are helpful :)

Answer: 6 days
Explanation: If he washes 75 cars in 5 days; and you need to find how many days it takes to wash 90 you do 75 divided by 5 which is 15; so he washes 15 cars in a day, then do 90 divided by 15 which is 6 days

Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
