Answer:

Step-by-step explanation:
The given expression is
![\sqrt[3]{x^{7} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%20%7D)
There's a exponent which relates fractional exponents and roots, that is
![\sqrt[n]{x^{m} } = x^{\frac{m}{n} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%20%7D%20%3D%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%7D)
So, if we apply this property, the results would be
![\sqrt[3]{x^{7} }=x^{\frac{7}{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%20%7D%3Dx%5E%7B%5Cfrac%7B7%7D%7B3%7D%20%7D)
Therefore, the right answer is the third choice 
Answer: No it's not possible to form a triangle
Why not? Because the shorter sides 2 ft and 3 ft don't add to a result longer than 7 ft
2+3 = 5
For a triangle to be possible, the sum of any two sides must be larger than the third side. Refer to the triangle inequality theorem.
Answer:
Shayla is incorrect because if you add them it would be 8r+r2
Step-by-step explanation:
You should probably double check because the question it a little confusing and I could always be wrong.

Answer:
I agree with both.
Step-by-step explanation:
If it's $3 per dozen that would be $0.25 per muffin because
3 ÷ 12 = 0.25
And if Andre has $2 than he can only afford 8 muffins because
0.25 x 8 = 2
And if Elena wants 16 muffins
16 x 0.25 = 4
So she will have to pay $4.
Hope this makes sense and helps!
