I would first suggest turning them all to one thing, like all decimals, or fractions. I chose decimals.
5.2, -5.6, 3.9, √21. To solve the square root, you have to simplify it. There is the square root of 3, times the square root of 7 which gets 21. These can't be simplified, so we can't simplify through that. But, the closest whole number that is a square root is 16. You can check by multiplying the same number together twice. Doing this will get you about 4.58
5.2, -5.6, 3.9, and ≈ 4.58. This is a simple ordering problem now.
It ends up as -5.6, 3 9/10, √21, 5.2
There are 2 decimals, one negative. There is one square root, and one mixed number. The square root is an infinite decimal when simplified

Answer:
Step-by-step explanation:
The answer is 3.4 as a decimal
Please note that dilation does not affect angles. Thus, if an image is dilated the angle remains the same and does not change.
Therefore, even if 
is dilated to 
by a factor of 1.5 (or by any factor for that matter), the linear dimensions of the original triangle will either get stretched or get shrunk by a factor of 1.5 but the angles of the original triangle will not be affected in any case.
Please note that this is true for all two dimensional geometric shapes.
It is a 4 out of 52 chance.
You can subtract 4 from 13 then subtract 4 again
