Answer:
3x[2] + 5x +2
^
(power)
Since order does not matter, you use a combination and not a permutation, so the first one is true, which means the second one is not true.
The probability of choosing two diamonds and three hearts can be represented by (13C2 * 13C3)/52C5, which is 0.0086, not 0.089, so the third one is not true.
The probability of choosing five spades and the probability of choosing five clubs are represented by the same thing, 13C5/52C5, which is roughly 0.0005, so the fourth one is not true but the fifth one is. So the answer is the first and fifth one.
For 44- 3x-14=2x+10. So x=24
For 45- 6x=90. So x=15
For 46- 7x+5=180. So x=2
I dont know 47. Sorry
A possible answer for #12 could be 12.

IT'S OBVIOUSLY LESS THAN 1 M.
1 m = 100 cm
It's LESS.
