What is the greatest common factor (gcf) of the numerator and denominator of the rational expression below? 5x+10/x^2-x-6 a. x b. x - 3 c. x + 2 d. 5

The GCF of given rational expression is x+2

C is correct.

Step-by-step explanation:

Given:

Here we have rational expression. We need to find the GCF (greatest common factor) of rational expression.

Factor numerator:

Factor Denominator:

Now we will see common factor from numerator and denominator.

Common factor is x+2

Hence, The GCF of given rational expression is x+2

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
