7(4*3)= 7(3*4) is it distributive if not what is it

Hey there!

That is not the distributive property. That is the commutive property. The commutive property states that if ab=c, then ba=c.

Let me know if 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
