I'm going to take a guess regarding what you meant to type in:
<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6
3(x+3) 6x+5
becomes E(x) = ----------- * ------------
x-9 5x+6
This cannot be reduced.
Try again to share this problem. Thank you.

Answer:
3 and 7
Step-by-step explanation:
For problems like these I take the largest number in this case 10, and start writing out what 2 numbers would give me 10. 0+10, 1+9, 2+8, 3+7...while doing that I subtract the numbers as well. thus 3+7=10 3-7=-4
You multiply all of them and you get 272!
The greatest common factor is 5x^2 so:
5x^2(x^2-1) (now notice that the parenthetical term is the difference of perfect squares)
The rule for factoring difference of squares is: a^2-b^2=(a-b)(a+b) so:
5x^2(x+1)(x-1)
Answer:
a=27.807
Step-by-step explanation:
Its simple, set it up for law of sine which is sinA/a = sinB/b
Sin108/a = Sin20/10
