Math Problem Statement
Solution
This image appears to be a set of math problems in Vietnamese. It includes two main tasks, with the first one involving two separate parts:
-
The first problem involves solving a word problem using an equation. It describes a mixture of two substances, where the total mass and volume are known, and you need to find the density of each substance. The equation will be based on the weighted average density formula.
-
The second problem involves solving a quadratic equation and calculating a specific expression involving the roots of the equation.
The second task is about a geometric problem involving a triangle, where you're asked to prove a relationship using the altitudes and some specific properties of the triangle.
Would you like me to solve any of these problems in detail?
