Answer:
option 4
Step-by-step explanation:
(f*g)(x) =(x² + x+ 1)*(x² - x -1)
= x²*(x² - x -1) + x(x² - x -1) + 1*( x² - x -1)
= x²*x² - x²*x -x²*1 + x*x² - x*x -x*1 + x² - x -1
= x⁴ - x³ - x² +x³ - x² - x + x² - x -1
= x⁴ - x³ + x³ - x² - x² + x² - x - x - 1
= x⁴ - x² - 2x - 1
The five hotdogs cost 1.75 ×5 = 8.75$
then 10-8.75=1.25$
he will get back with 1.25$

We have to calculate how much time they spend in a day.
Jake:
3/4 hour-----------------------2 days
x---------------------------------1 day
x=(3/4 hour*1day) / 2 days=3/8 hours
Kyile:
1/4 hour------------------------6 days.
x----------------------------------1 day
x=(1/4 hour * 1 days) / 6 days=1/24 hours
3/8 hours>1/24 hours, therefore
Jake sepent more time total working on his project.
