Meh

ok so when have sqrt, try to square both sides
\sqrt{2x-1}=2+ \sqrt{x-4}
square both sides
2x-1=4+4 \sqrt{x-4}+x-4
2x-1=x+4 \sqrt{x-4}
mnus x both sides
x-1=4 \sqrt{x-4}
square oth sides
x^2-2x+1=16(x-4)
x^2-2x+1=16x-64
minus (16x-4) from both sides
x^2-18x+65=0
factor
(x-5)(x-13)=0
set each to zero
x-5=0
x=5

x-13=0
x=13

x=5 and 13

From a pack of 9 cards numbered 1-9, three cards are drawn at random and laid on a table from left to right.
Andreas93 [3]
Answer: 1/6
Explanation: Since we need to draw three cards from a pack of 9 and the digits require an order, then our sample space becomes: 9P3.
Now, we don't care about picking an order when picking three cards to analyse, as there is only 1 way in arranging the three cards in descending order.

Thus, we get:

\frac{^{9}C_3}{^{9}P_3} = \frac{1}{6}
