From 2:30-3:30 is 1hr and from 3:30-4:00 is 30 min from 4:00-4:15 is 15 minutes
Add up these time you get 1hr and 45min
Move everything to one side and factorize by grouping.
x⁴ - 4 = x³ + 2x
x⁴ - x³ - 2x - 4 = 0
(x⁴ - 4) - (x³ + 2x) = 0
(x² - 2) (x² + 2) - x (x² + 2) = 0
(x² - x - 2) (x² + 2) = 0
(x - 2) (x + 1) (x² + 2) = 0
Then
x - 2 = 0 or x + 1 = 0 or x² + 2 = 0
x = 2 or x = -1 or x² = -2
If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).

Answer:
126
Step-by-step explanation:
I = prt
I = (600)(0.07)(3)
I = 126
Answer: 126
Answer:
Step-by-step explanation:
no of yellow golf=1/7*28
=28/7
=4
no of white golf=5/7*28
=140/7
=20
no of green golf=total golf-(yellow golf + white golf)
=28-(4+20)
=28-24
=4
therefore he has 4 green balls
