A rectangle has a height of 4 and a width of 2x^2-x

Perimeter:  

Area:  

Step-by-step explanation:

I will assume the question asks for perimeter and area of the rectangle with given dimensions.

The height is "4"

The width (assuming) is ""

First, the perimeter:

Perimeter is sum of all 4 sides of a rectangle, so we have 2 widths and 2 lengths, we sum them up:

Now, the area:

Area is the height times width, so it will be:

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

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
