I’m trying to understand what it’s asking not sure if this is correct or not

Step-by-step explanation:

First of all, the term multiple needs to be defined.

When a number is multiplied by another number other then zero, we get the multiple as result.

i.e. Multiples of 2 are: 2, 4, 6, 8, 10

To find the Least Common Multiple of numbers, we list the multiples of those numbers and then the samllest factor that is common in both lists is chosen as least common multiple.

1. 10, 20

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80

Multiples of 20: 20, 40, 60, 80, 100

Least Common Multiple: 20

2. 3, 9

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27

Multiples of 9: 9, 18, 27, 36, 45

Least Common Multiple: 9

3. 12, 24

Multiples of 12: 12, 24, 36, 48, 60, 72

Multiples of 24: 24, 48, 72, 96

Least Common Multiple: 24

4. 25, 45

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250

Multiples of 45: 45, 90, 135, 180, 225, 270, 315

Least Common Multiple: 225

5. 5, 10

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40

Multiples of 10: 10, 20, 30, 40, 50, 60

Least Common Multiple: 10

6. 49, 56

Multiples of 49: 49, 98,147, 196, 245, 294, 343, 392, 441

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448

Least Common Multiple: 392

This method of finding LCM is brute force and requires more time.

Another method is by using GCD(Greatest Common Divisor). It is the greatest positive integer number which completely divides all the numbers in consideration.

The product of the numbers is divided by their GCD to find the LCM.

i.e. for Q6

GCF(49, 56) = 7

LCM(49,56)=  (49*56)/7

=2744/7=392

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
