5. What is the length of LN?

6. What is the length of MN?

Part 1)

Part 2)

Step-by-step explanation:

Part 1) What is the length of LN?

To find out the length LN subtract the coordinate of L from the coordinate of N

so

Part 2) What is the length of MN?

To find out the length MN subtract the coordinate of M from the coordinate of N

so

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
