Wendy paints a rectangular wall that is 10.5 feet tall and 9.2 feet wide. what is the area of the wall that she paints?

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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
