2 servings because one serving is 4%, so you would need would need to double that, or multiply it by two.
Answer:
-10
Step-by-step explanation:
Let x = number
10 less than a number is the same number doubled
x-10 = 2x
Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
The 5 rounds to 3 so it is 4.3
A cubic equation can only have at most 3 roots. You already have 3 roots. x = 3 ,x = -2i , and x = 2i
