No worries, zegroes....I think it does it for eveyone.....just a "ghost in the machine"  perhaps....!!!!

Not all fractions ger smaller.....only those between 0 and 1

For example  (1/4)^2   = 1/16   ....but....  (3/2)^2  =  9/4 ...  And  3/2 = 1.5   but 9/4  = 2.25....so....this gets larger

[This also assumes that the exponents are positive integers ]

This is the graph of x^2 shifted up 4 units......and x^2 has a vertex of (0,0).....so....x^2 + 4 has a vertex at (0, 4)

1 meter   = 39.37 in

So......

39.37 / 12  = about 3.28 ft.

Let's  walk this through step-by-step

[ 2x - 4] / 3   + 2   = 1/2      multiply through by the common denominator of 2 and 3   = 6

2 [2x - 4] + 12  = 3              subtract 12 from both sides

2 [2x - 4 ]  = - 9    simplify

4x - 8   = -9          add 8 to both sides

4x   = -1               divide 4  by both sides

x  =  -1/4

What is the question  ???

Ther are 12 counters....7 are not red....so....the probability that a red one is not selected = 7/12

Well thought out answer, Z-Man......the admin may be working on obtaining an app that screens out some of this inappropriate garbage....you're right, of course......there are always going to be idiots......you can't screen all of them out.....!!!!
