What the greatest common factor of 15 and 42

3

Step-by-step explanation:

Given in the question two integers

15 and 42

GCF

3 | 42 , 15

  | 14 , 5

The factors of 15 are: 1, 3, 5, 15

The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42

Since , only 3 is common so the greatest common factor is 3.

GCF=3

Step-by-step explanation:

The given numbers are;

We express each number as product of primes to obtain

and

The greatest common factor is the product of the least powers of the common factors.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
