Answer:
C
Step-by-step explanation:
We want to solve the equation:

Using the quadratic formula. The quadratic formula is given by:

In this case, <em>a</em> = 1, <em>b</em> = 2, and <em>c</em> = 7.
Substitute:

Evaluate:

Simplify the square root:

Hence:

Simplify:

Hence, our solutions are:

Our answer is C.
Answer:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
