Answer:
Option C
Step-by-step explanation:
6x² +5x + 1
6x² + 3x + 2x + 1
3x(2x + 1) + 1(2x + 1)
(3x + 1)(2x + 1)
Answer: No triangle
Step-by-step explanation:
The given dimensions of triangle : 4.8 cm, 2.1 cm, and 2.6 cm
- The famous triangle inequality says that in any triangle the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.
But
It means the sum of two sides (2.1 and 2.6) is less than the third side (4.8).
Therefore by triangle inequality, no triangle can be possible by the given measurement.
The pH of the substance is 3.
<u>Explanation:</u>
Given:
Concentration of hydrogen ion, [H⁺] = 10⁻³M
pH = ?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
pH = -log [H⁺]
pH = -log [10⁻³]
pH = 3 log [10]
pH = 3
The pH of the substance is 3 and since the pH is less than 7, the substance is acidic in nature.
