The length of a rectangle is 3 m less than twice the width if the area of the rectangle is 66 5 m² find the dimensions

Let the width be x.

Then,Length = ( 2x - 3 ) m

According to the question,

Area of rectangle = 665 m² [ Given ]

Formula: Area of rectangle = Length × Width

By split middle term

Note: Ignore negative number.

Now,

Width of a rectangle = 19 m

Length of a rectangle = 2x - 3 = 2 × 19 - 3 = 38 - 3 = 35 m

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.
