2a2+2a2 = 4a2
There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).

2X + 3
No, it is not. A perfect square is the product of two equal integers; i.e. 9 is a perfect square. It can be expressed as 3*3. There is no number that when multiplied twice equals 50.
Any one dimension increased by 2, or any two dimensions increased by the square root of 2 orall three dimensions increased by the cube root of 2.

The answer is 12.32 - 8 = 24. 24 ÷ 2 = 12.Hope this helps!

There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
Any one dimension increased by 2, or any two dimensions increased by the square root of 2 orall three dimensions increased by the cube root of 2.
Any one dimension increased by 3, or any two dimensions increased by the square root of 3 or all three dimensions increased by the cube root of 3.
