Answer:

diameter = 8 miles

Step-by-step explanation:

Area of a circle = πr²

πr² = 50.24

3.14*r² = 50.24

r²= $\frac{50.24}{3.14}\\\\$

r² = 16

r² = 4²

r=√4²

r = 4 miles

diameter = 2 *radius = 2*4 = 8 miles

Answer:

7y + 24

Step-by-step explanation:

Think of the negative sign to the left of the parentheses as being -1. Then apply the distributive property. The effect of a negative sign to the left of parentheses or a 1 to the left of parentheses is that each term inside the parentheses changes sign.

-(-7y - 24) = -1(-7y - 24) = (-1)(-7y) - (-1)(24) = 7y - (-24) = 7y + 24
