Answer:

Step-by-step explanation:
1.
2 yellow marables of 10 all marables

2.
1 yellow marable of 9 all marables


This problem is very simple. All you have to do is add 10 and 9. The correct answer is D.
Multiplicity is how many times the root (or zero) is repeated
example, in

the root b has a multiplicity of n and the root d has a multiplicity of m
first we need to get the roots into

for (3x+5), we need to force factor out the 3 to get

factor the other one

but it is

which is equivilent to

which simplifies to

so we get

so the roots are -5/3 multiplicity 1 and 3 multiplicity 4
3 has a multilicity of 4
The answer is x = -2 +- sqrt 7
