The greatest common factor is 4r so

4r(d-4)

4dr-16r

Remember, the first step in doing this is finding the GCF, or greatest common factor.

Look at both equations, and see what it is.

We see that it is 4.

Look for any variables that are found in both numbers.

r is found in both numbers, so 4r is the GCF.

4dr-16r

What is 4r divided by 4dr? It would be d.

What is -16r divided by 4r? -4

So, our equation now looks like this:

4r(d-4)

So, the last one is correct.

goblinko [34]

Answer:

Below

Step-by-step explanation:

The length of this triangle is 3x+1 and the width is x.

The perimeter P is:

P= 2(3x+1)+2*x

P= 6x+2+2x

P= 8x+2

Let's evaluate it when x=1/2

●1/2 =0.5

P= 8*0.5+2 =4+2= 6 ft

●●●●●●●●●●●●●●●●●●●●●●●●

The area A is:

A = (3x+1)*x

A= 3x^2 +x

Let's evaluate it when x=0.5 feet

A= 3*0.5^2 +0.5

A= 3*0.25+0.5

A= 0.75 +0.5

A= 1.25 ft^2

A scatterplot is used to display data for a runner where x is the number of miles run, and y is the time, in minutes, that it ta

larisa [96]

The interpretation of y = 9.5x is that: (a) For each 1 minute, the runner ran 9.5 miles.

<h3>How to interpret the equation?</h3>

The equation of the line of best fit is given as:

y = 9.5x

Divide both sides by x

9.5 = y/x

From the question, we have:

x ⇒ number of miles run
y ⇒ time

This means that:

9.5 = number of miles run/time

Hence, the interpretation of y = 9.5x is that: (a) For each 1 minute, the runner ran 9.5 miles.
