I’m not sure, you should install photomath tho it should say
Answer:
I think it should be 
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would
where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get
which would become
.
The equation for this statement:
2x – 14 = 6
=> 2x = 6 + 14
=> 2x = 20
=> x = 20/2
=> x = 10
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 :

It is given that, the zeroes of a quadratic function are 3 and 12. It means they must be factors of it such that,

So, we can write as :

Multiplying both factors,

So, the above equation is a quadratic function whose zeroes are 3 and 12.
