Answer:
Cubed
Step-by-step explanation:
You can think of it as the volume of a cube where the volume is x to the third power (
, let x = side of the cube) to help you remember. This also goes the same for x to the second power (squared) where it can represent the area of a square which is x².
Hope this helps :)
Answer:
See Bottom
Step-by-step explanation:
3 goes into 19 6 times, the closest, because 6 x 3 = 18, and that is the closest that you can go and fit 3 into 19
Hope this helps!
Answer:
The above equation is a quadratic function whose zeroes are 3 and 12.
Step-by-step explanation:
The general quadratic equation is given by :
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
It is given that, the zeroes of a quadratic function are 3 and 12. It means they must be factors of it such that,
![(x-3)=0\\\\(x-12)=0](https://tex.z-dn.net/?f=%28x-3%29%3D0%5C%5C%5C%5C%28x-12%29%3D0)
So, we can write as :
![(x-3)(x-12)=0](https://tex.z-dn.net/?f=%28x-3%29%28x-12%29%3D0)
Multiplying both factors,
![(x-3)(x-12)=0\\\\x^2-12x-3x+36=0\\\\x^2-15x+36=0](https://tex.z-dn.net/?f=%28x-3%29%28x-12%29%3D0%5C%5C%5C%5Cx%5E2-12x-3x%2B36%3D0%5C%5C%5C%5Cx%5E2-15x%2B36%3D0)
So, the above equation is a quadratic function whose zeroes are 3 and 12.
