Answer: A, C and E.
Step-by-step explanation:
The expressions 1/2 + 3c + 4/5 is thesame as writing 3c + 1/2 + 4/5, 1/2 + 4/5 + 3c, 4/5 + 1/2 + 3c, 3c + 1/2 + 4/5.
In all the expressions written above, the only thing that can be seen is just that the position of the numbers were alternated.
Therefore, based on the options given, the answer will be A, C, and E.
Answer: A whole number.
Step-by-step explanation: This is because the numerator and the denomenator are both the same. Meaning, we can change it into a whole number, which is 1.
You would multiply 10 and 15 then divide by 2
So use the <span>Pythagorean Theorem. A^2 + B^2 = C^2 10^2 +12^2 = 15.6 hope this helps.

Well you're correct in saying that it's because it's a regular hexagon and so if one triangle is an equilateral, then all of them are. If you want a mathematical way to prove it, then if the point around N is 360° because it's around a point, then you can divide 360 by 6 (6 triangles) to get 60°. That is the angle of ENX, and therefore it is an equilateral triangle because all angles in an equilateral triangle are 60°. I hope this helps!
