Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are


From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.
Answer:
second one
Step-by-step explanation:
Answer:
Step-by-step explanation:
The functions are written in slope-intercept form.
The graph crosses the y-axis at (0,-2), so the y-intercept is -2.
You can eliminate D because its y-intercept is +2, not -2.
(1,1) and (0,-2) are points on the line.
The slope of the line is (-2-1)/(0-1) = 3
You can eliminate B because its slope is ⅓.
Eliminate C because its slope is -3, not 3.

- First, line up the numbers and write down the subtracting symbol or addition symbol.
- Second, add the ones place
- Then, add the tens place
- If numbers go onto the hundreds place then add that but if not then your done.
