What is the greatest common factor of 343, 49, and 196? 49 14 7 343 3?

1 answer:

4 0

From the prime factorization of 49, we get 7*7. From 196, we get 2*2*7*7. From 343, we get 7*7*7. The greatest "overlap" or common factors are 7*7, or 49.

Thus, the greatest common factor is 49.

What's the distance between (0,2) and (0,8)?

N76 [4]

Answer:

6 units

Step-by-step explanation:

The distance between two points can be calculated with the formula

$\boxed{\textcolor{steelblue}{\text{Distance between 2 points}= \sqrt{(y_1 - y_2)^{2} + (x_1 - x_2)^{2} } }}$

However, since (0, 2) and (0, 8) have the same x coordinate of 0, the distance between them is the difference in their y-coordinates.

Distance between (0, 2) and (0, 8)

= 8 -2

= 6 units
