STEP-BY-STEP SOLUTION:
= x^2 - 13x + 30
= x^2 - 10x - 3x + 30
= x ( x - 10 ) - 3 ( x - 10 )
= ( x - 10 ) ( x - 3 )
FINAL ANSWER:
Therefore, the answer is:
C. x - 10

Answer:
The concentration of hydrogen ions in moles per liter (M) is 
Step-by-step explanation:
As we know
The hydrogen ion concentration of any solution at pH is given by

Substituting the given values in above equation, we get -
mol/l
The concentration of hydrogen ions in moles per liter (M) is 
I think this is the answer to your question And also the solution
B= number of beakers which there are 450
t= number of test tubes
the answer is 1.46
Answer:
Look at the step by step :)
Step-by-step explanation:
In reference to the unit circle, 120 degrees is directly corresponding to 2pi/3. Mathematically, you can do 120 x pi/180 and simplify (which gets you to 2pi/3) to figure this out. 5pi/6 radians is equal to 150 degrees. Mathematically, you can do 5pi/6 x 180/pi (which gets you to 150 degrees). Therefore, the two measurements are 30 degrees or pi/6 radians apart from one another
