m-2+1-2m+1
When simplified: -m
m2 + 12m + 20 = ( m + 2)(m + 10)
(m - 2)(m - 10)
m2 + 8m - 65 = (m + 13) (m - 5)
m2 + 4-1/2 m2 + 1 / 4+1/2 m2 + 1 / (square root of 4) m2 + 1/2

To find the volume needed, you can use the formula: M1V1 = M2V2. Here, M1 = 12M (initial concentration), V1 = volume of 12M HCl solution needed, M2 = 0.100M (final concentration), and V2 = 250 mL. Rearranging the formula, V1 = (M2 * V2) / M1 = (0.100M * 250mL) / 12M = 2.08 mL. Therefore, you will need 2.08 mL of the 12M HCl solution to prepare 250 mL of 0.100M solution.
m2 (-1-3) is an expression, neither an equation nor an inequality. Therefpore, there is nothing to solve.
Area of traingle = Base * Height / 2 = 18*12/2 = 108 m2
m2 (-1-3) is an expression, neither an equation nor an inequality. Therefpore, there is nothing to solve.
Due to the limitations of the browser which is used to post questions to this site, most mathematical symbols are not visible. It is, therefore, not possible to make out what the expression is meant to be. You could try to resubmit it using words or phrases, like "plus", "divided by".
