Answer:

V=4x^3-30x^2+54x

Step-by-step explanation:

From the question we are told that

Breath of cardboard h=6

Length of cardboard l=9

Let x be the height when fold

Generally the new rectangle is  mathematically given as

Breath h'=(6-2x)

Length l'=(9-2x)

Generally the Volume of tray is mathematically given as

V=L*B*H

V=(9-2x)*6-2x*x

V=x(4x^2-30x+54)

V=4x^3-30x^2+54x

Write an equation of the line that passes through the point (-6, -9) with slope-5.
Art [367]

Answer:

y+9=-5(x+6)

Step-by-step explanation:

We are being asked to write the equation in point-slope form:

y-y_1=m(x-x_1) where m = slope and the first point = (x_1,y_1)

In this case, the slope is -5 and the point is (-6,-9) so the equation will be:

y+9=-5(x+6)

The output is four times the input
juin [17]
O=4i (is that was you were asking about) 

edit: sorry that wasn't very detailed say if the input is 4 the output will be 16 or if the input is 100 the output will be 400. So mainly what ever the input is multiply it by 4.
