Answer:
( x + 2 ) and ( x - 11 )
Step-by-step explanation:
x² - 9x - 22 = 0
x² + 2x - 11x - 22 = 0
x ( x + 2 ) - 11 ( x + 2 ) = 0
( x + 2 ) ( x - 11 ) = 0
Factors of x² - 9x - 22 are ( x + 2 ) and ( x - 11 ).
Answer:
1. no

i hope this helps :)
8/9 + 1/7= 56/63 + 9/63= 56+9= 65/63 = 1 2/63
it equals 1 and 2 over 63
Usually people love to travel via boat including me :). At some point you need to get off from boat.
Question is asking about what should we say when we get off from boat. There can be lots of answers for this question because there is no fixed rule to leave the boat.
You may say good bye or wish the people who are still on the boat.
In fact you are free to say anything in the world. :)
Notice they are all right triangles. You will need Pythagorean theorem, which is a² + b² = c²
If you write down all the "equations" you can find, it is the following:
y² + 4² = x²
5² + y² = z²
x² + z² = 9²
Substitute them into one equation:
y² = x² - 4²
z² = 5² + (x² - 4²) <em>Notice that the y² is replaced with what you found </em><em>above</em>
x² + (5² + x² - 4²) = 9² <em>Notice that the z² is replaced with what's </em><em>above</em>
Now that it is just one line with one variable, you should be able to find value of x easily.
The answer is 6 if my calculations are correct.
