Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!

Since both equations are equal to y, they must equal each other. So set them to equal each other.
28 + 0.05x = 25 + 0.07x (✿ ♥‿♥)
Let's start by subtracting 25 from both sides!
3 + 0.05x = 0.07x (28-25=3, 25-25=0)
Now let's subtract 0.05 from both sides O(≧▽≦)O
3 = 0.02x
We need this x by itself, so let's get rid of it. Do this by divide both sides by 0.02 ( ´_⊃`)
150 = x
So x = 150. Let's test this. Substitute 150 in for x in both equations! \(^○^)人(^○^)/
28+0.05(150) = 25+0.07(150)
28 + 7.5 = 25 + 10.5 (0.05*150=7.5, 0.07*150 = 10.5)
35.5 = 35.5
It works! (ノ◕ヮ◕)ノ*:・゚✧
So x = 150
Yo mean sqrt 27 or √27
remember
√(xy)=(√x)(√y)
√27=(√9)(√3)=(3)(√3)=3√3
The answer of the question is 75
Can you be more specific about what is P(5)? The probability would probably be around five though.
