John is building a rectangular pen for his sheep. The length of the pen is 5 more than 8 times the width of the pen. Complete an equation for the area of the pen, where w is the width of the pen.

Area = w x (5+ 8 w)

Step-by-step explanation:

Recall the formula for the area of a rectangle:   Area=with x length

You are suggested to use "w" to represent the width of the pen.

Now, they give you information about the length of the pen in word form.

We are converting those words into an algebraic expression:

"The length of the pen is 5 more than 8 times the width of the pen"

Length = 5 + 8  w

So we replace the length of the pen with this expression in the area formula:

Area = w x (5+ 8 w)

Hope this answer helps you :)

Have a great day

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

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
