LCD(34, 45, 23) = LCM(4, 5, 3) = 22×3×5 = 60
34 = 4560
45 = 4860
23 = 4060
7+2=2+6 because 7+2=8 and 2+6 is = to 8 as well
Answer:
9
Step-by-step explanation:
First, find <em>x</em>. Since <em>x</em> is the average of the three number, add the three up and then divided by three. Thus:

<em>y</em> is the cube root of 8. Thus:
![y=\sqrt[3]{8}=2](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B8%7D%3D2)
So:

Step-by-step explanation:
just guess and see
