Answer: The required ratio would be 3 miles : 4 minutes.

Step-by-step explanation:

Since we have given that

Speed of a cheetah = 45 miles per hour

So, it means

Distance = 45 miles

Time = 1 hour = 60 minutes

So, the ratio of the distance it travels to the time it takes would be

Distance : Time

$45\ miles:60\ minutes\\\\=3\ miles :4\ minutes$

Hence, the required ratio would be 3 miles : 4 minutes.

Consider the rational expression (IMAGE ATTACHED)

Keith_Richards [23]

Answer:

3x² is a term in the numerator
x + 1 is a common factor
The denominator has 3 terms

Step-by-step explanation:

You can identify terms and count them before you start factoring. Doing so will identify 3x² as a term in the numerator, and will show you there are 3 terms in the denominator.

When you factor the expression, you get ...

$\dfrac{3x^2-3}{3x^2+2x-1}=\dfrac{3(x^2-1)}{(3x-1)(x+1)}=\dfrac{3(x-1)(x+1)}{(3x-1)(x+1)}$

This reveals a common factor of x+1.

So, the above three observations are true of this rational expression.
