d-n= Total number of wrong answers

d- (d-n) = Total number of correct answers

price: 10 for each correct answer, so:

price: [d-(d-n)]*10

Therefore:

aₙ = [d-(d-n)]*10

Find the area of the composite shape
Alexxandr [17]

Answer:

13.735 ft^{2}

Step-by-step explanation:

Area of a circle.

A=\pi r^{2}

r=d/2\\r=8/2\\r=4

A=\pi \times 4^{2}

A=16\pi

A \approx 50.2654824574

Area of a square.

A=s^{2}

A=8^{2}

A=64

Subtract the area of the square with the area of the circle.

64-50.2654824574

= 13.7345175426

I hope it helps.

Brainliest much appreciated.
