Hope there are
3(x-4) >= 5x^2 or this 2 from the end what mean ?
3x-12 >=5x^2
0>=5xˇ2 -3x +12
5x^2 -3x +12 =0
D = 9 -240 = -150 so what mean that this equation has not real solutions
Answer:
The diameter of the pizza = 14 in
Radius of the pizza = (14/2)in = 7in
Area of a whole pizza =
πr^2
=( 22/7 × 7^2)in^2
=( 22/7 × 49)in^2
154 in^2
Area of a half pie =( 1/2 × 154)in^2 = 77in^2
Area of one of 8 slices = (1/8 × 154)in^2 = 19.25in^2
Hope it helps
Completing the squares tells us exactly what square root we will need to calculate our answer.
Using the formula below you can find these answers:
![A(x-h)^2 + K = 0 (x-5)^ 2 = - K/A ](https://tex.z-dn.net/?f=A%28x-h%29%5E2%20%2B%20K%20%3D%200%0A%28x-5%29%5E%202%20%3D%20-%20K%2FA%0A)
Does this make sense?
