PLEASE HELP ME WITH THIS QUESTION WILL GIVE BRAINLIST TO BEST ANSWER

Answer 1

It’s more like multiples of 3. 9 is 3 times 3, 21 is 7 times 3, basically increased by 4. Same way, 2 times 3 becomes 6 times 3, which should be 18

Answer 2

Basically, we have two similar figures so the ratio of their corresponding sides is going to be proportional as well.

It goes here,

• 9/21 = 6/x

Cross multiply it

• 9x = 21 × 6

Drag out x on the other side of the equation

• x = 21 × 6/9
• x = 7 × 2
• x = 14

And yeah, that's what we were looking for.
