Answer:

n = 8.

Step-by-step explanation:

n^2 × constant nunber = W.

5^2 × constant number = 175. So the constant number is 7.

When W = 448, n^2 = W/7, n^2 = 64.

Thus, n = 8.

Answer:

Step-by-step explanation:

Change the mixed numbers to improper fractions

7 $\frac{1}{5}$ = $\frac{36}{5}$

6 $\frac{2}{5}$ = $\frac{32}{5}$

The subtraction is then

$\frac{36}{5}$ - $\frac{32}{5}$

Both fractions have a common denominator so subtract the numerators leaving the denominator

= $\frac{36-32}{5}$ = $\frac{4}{5}$ → A
