The Cutting Edge frame shop makes a mat (the border around a picture) by cutting out the inside of a rectangular board. The dimensions of the entire board are length=2x-3 and width=x+8. The dimensions of the white cutout are length=2x-7 and width=x+4. Find the length and width of the original board if the area of the black mat is 184 square inches.

3024 rhe base is what up in worry about

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
