Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is
There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
Answer:
5 days
Step-by-step explanation:
Sohan can do the whole thing in 10 days
he worked 5 days so he did half
and Mohan did the other half in 5 days
so their speeds are same
so if they worked together they'd do it in half the time
i.e 5 days
Answer:
A. 5
Step-by-step explanation:
Let n = number
(3n)+6 = 5n-4
Subtract 3n from each side
(3n)-3n+6 = 5n-3n-4
6 = 2n-4
Add 4 to each side
6+4 = 2n -4+4
10 = 2n
Divide by 2
10/2 = 2n/2
5 =n
√36/16 is the rational number. Mark brainliest please
