I KEE asking so many questions lol I just don’t understand!

Perimeter = 20

Step-by-step explanation:

Perimeter = 9 + 5 + 6

Best Regards!

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
