60 divided by 12 is 5, so you can eliminate A and D. The answer is C because you must buys more to be sure that you can give each child at least one candy bar.
2.25X5= 11.25
2 1/4 turns into 2.25 as a decimal, and a pentagon has 5 equal sides, so you take 2.25 and multiply it by 5 to get your answer
11.25ft

Answer:
C
Step-by-step explanation:
Recall the exponent property that:
![x^{\frac{1}{n}}=\sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%7D)
And vice versa:
![\sqrt[n]{x}=x^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Thus:
![\sqrt[3]{500} =(500)^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B500%7D%20%3D%28500%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
The answer is C
3x²+5x=2
x(3x+5)=2
x=2 or 3x+5=2
x=3/5
