(-12)-²= ?
Pls help :)

Step-by-step explanation:

The formatting is a little off on my computer, so please correct me if I am wrong, but your question is .

To solve this, we must square the (-12) which means we do -12*-12 and the negative signs cancel out. This equals to 144, but since it is a negative square, we put this in the denominator like so .

I hope this helps!

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
