Answer:
C.
and
Step-by-step explanation:
You have the quadratic function
to find the solutions for this equation we are going to use Bhaskara's Formula.
For the quadratic functions
with
the Bhaskara's Formula is:


It usually has two solutions.
Then we have
where a=2, b=-1 and c=1. Applying the formula:

Observation: 

And,

Then the correct answer is option C.
and
Step-by-step explanation:
Plan B:
2:5 = 0.4 red to 1 white
1:4 = 0.25 red to 1 white
Students might also scale up using part-to-whole-ratios and come up with 35 parts total and 14 parts red for Plan A and 35 parts total and 7 parts red for Plan B.
