A rectangular yard has dimensions 10 meters by 12 meters. In the middle of the yard is a rectangular pond of 48 square meters, leaving a uniform walkway around the pond. Write a quadratic equation in standard form to find the width of the walkway. Will give brainlest

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
