Answer:
first one
28.26 im not 100% correct i dont think
<span>Well, the number is decimal form, is in the thousandths place, so the denominator, would be 1000's:
<em><u>0.275 = 275⁄1000</u></em></span><em><u> </u></em>
<span>Then, you have to Simplify 275⁄1000 In which, you would get: <em><u> 11⁄40</u></em></span><span><em><u> </u></em></span>
Confusing question but I would get 0, as if you have 4cm, that squared = 16cm^2. Therefore if it were increasing anymore, then you would not be able to get a value of 16.
It would be positive 1/3 because if you move to the right one on your bottom point and up 3 it gives you +1/3
