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'

Step-by-step explanation:
Answer:
x = 5/8 for 5x - 3 = (1/5)x
Step-by-step explanation:
To find x, we want to isolate our 3 from our x-values. You can add three to both sides of the equation and get it to the other side and then subtract 1/5x from 5x.
(5x - 3) + 3 = ((1/5)x) + 3
5x = (1/5)x + 3
5x = (25/5)x
((25/5)x) - (1/5)x = ((1/5)x + 3) - (1/5)x
(24/5)x = 3
From here, you would want to solve for x. This would mean multiplying 3 by 5 and dividing your product by 24.
5*3 = 15
15/24 = 5/8 = x
Hope this helps!
