The area of a square is 80 square inches. what is the length of one side in simplest radical form?

The measure of the sides is 4√5.

Step-by-step explanation:

In order to find this, we can set the side as x. Now we can square that and set it equal to 80.

x^2 = 80

x = √80

x = 4√5

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
