Answer:
can be expressed in nested form as 
Step-by-step explanation:
Considering the polynomial

Expressing the polynomial by nesting
So,

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

Step 3) Repeating the previous step until all terms are within the equation.
So,

Therefore,
can be expressed in nested form as

Answer:
40min
Step-by-step explanation:
Since the ratio is 2:16, we want simplify. both 2 and 16 are dividable by 2.
2 / 2 = 1
16 / 2 = 8.
Now we can use the ratio 1 mile per 8 min. We want the rate of how many min to miles, so we'd multiply 5 by 8 which equals 40.
Therefore it takes him 40min to run 5 miles.
Hope this helps!
