The perimeter of a rectangle is 28 the length of the rectangle is 2 more than the width find the length and width of the rectangle

P = 2L + 2W

P = 28

Width = W = x

Length = L = x + 2

28 = 2(x + 2) + 2x

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
