Two trees are in a garden. the 20-foot tree casts a shadow four feet long. if the other tree is 15-foot tall, how long will its shadow be?

1. 3 feet
2. 5 feet
3. 5 1/3
4. 8 feet

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
