Plug in 3 to x:
f(x) = 3³ - 7
Solve:
f(x) = 3³ - 7
f(x) = 3 · 3 · 3 - 7
f(x) = 9 · 3 - 7
f(x) = 27 - 7
f(x) = 20

To calculate the area of the circle, make sure to use the equation. A = Pi r^2, since the diameter is given divide by 2 to get the radius and plug into the equation.
Then locate the decimal place that is hundredths and round

Answer:
70 - 5√10 ft²
Explanation:
Perimeter is the distance around a two-dimensional shape.
area of rectangle: length x width
Here given:
length: (3√2 + 4√5) ft
width: (-5√2 + 5√5) ft
Solve for perimeter:
length x width
(3√2 + 4√5) x (-5√2 + 5√5)
<u>apply distributive method</u>
(3√2)(-5√2) + (3√2)(5√5) + (4√5)(-5√2) + (4√5)(5√5)
<u>multiply</u>
-15(2) + 15√10 -20√10 + 20(5)
<u>combine</u>
-30 -5√10 + 100
<u>simplify</u>
70 - 5√10
