If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2
The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.
Answer:
24.
Step-by-step explanation:
Because AD is equal to 18 that means that both parts together equal 18 divide 18 by 2, and you get 9. Same thing for AC and this time you get 15. Add them together and you get 24.
