The dimensions of a rectangle are 6m by 8m. how does the area of the rectangle change if the dimensions of the rectangle are doubled?

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

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

what are the answer choices given for this problem?
