Answer:
15
Step-by-step explanation:
-1 = 3
-2 = 6
-3 = 9
-4 = 12
-5 = 15
-6 = 18
It is all by 3.
To find the area of a square, use this formula-
A=a² where 'a' is the length of one side.
Since we know the area, and are trying to find the side length, then you would do the opposite-
a=√A
a=√40
√40≈6.32
The you would solve your other answers to compare. I started at the top, with choice one, and solved it this way-
2*√10
√10≈3.16
2*3.16≈6.32
So the answer would be choice 1, '2sqrt10'
The function changes at a constant rate, is the only correct answer that I can see.
What’s the question? Maybe then I can help.
