Answer:

Yes, because $x(x -4)$ is equivalent to $x^2-4x$

Step-by-step explanation:

$x(x -4)$ and $x^2-4x$

$x(x -4) = x^2 - 4x$

Hope this helps!

A candle is in the shape of a square prism. The candle is 16 meters high, and its volume is 960 cubic meters. Find the length of

madam [21]

Answer:

The length of each side of the square base is $2\sqrt{15}\ m$

Step-by-step explanation:

we know that

The volume of a square prism is equal to

$V=b^{2}h$

where

B is the length side of the square base

h is the height of the prism

we have

$V=960\ m^{3}$

$h=16\ m$

substitute and solve for b

$960=b^{2}16$

$b^{2}=960/16$

$b=\sqrt{60}\ m$

Simplify

$b=2\sqrt{15}\ m$

Five yards of material is needed to make

Mkey [24]

Answer:

The y-coordinate would be 17.5

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

y ----->material needed in yards

x ----> number of curtains

we know that

For y=5, x=2

Find the value of the constant of proportionality k

$k=y/x$

substitute the given values of x and y

$k=\frac{5}{2}=2.5$

The linear equation is equal to

$y=2.5x$

If the x-coordinate was 7

then

substitute in the equation x=7 and solve for y

$y=2.5(7)$

$y=17.5$

therefore

The y-coordinate would be 17.5
