Answer:

n =1.78

Step-by-step explanation:

2(5n-6)

2(n+1)

10n-12+4n+2=15

14n-10=15

subtract both sides by 10

14n=25

25/14

n=n =1.78571428571

What are the zeros of 3x²(x+π)³(x-4)²
Aneli [31]
Hi again!

The zeros are the values of x. This is where the graph intersects the x - axis. In order to find the zeros, replace y with 0 and solve for x.

The answer is x = 0, -π, 4

I am not sure what grade are you or the level, but for me, they sometimes asked me to find their multiplicities as well

The multiplicity of a root is the number of times the root appears.

So, the answer are
x = 0 and the multiplicity of 2
x = -π and the multiplicity of 3
x = 4 and the multiplicity of 2

Good luck with your studies!
