How to solve 5x-2y=3 y=2x

Answers

Answer 1
Answer: If y = 2x, you simply need to replace y with 2x, and then solve the equation normally. 

5x –2(y) = 3
5x – 2(2x) = 3
5x – 4x = 3
x = 3

Describe in Words how to find the area of the square given that each side is s inches long

Answers

The area of the square is s^2.

Final answer:

To find the area of a square, square the length of one side. For example, if the side length is 4 inches, the area is 4² = 16 square inches (in²).

Explanation:

To find the area of a square with a side length of s inches, you need to use the formula for the area of a square, which is Area = s², where 's' represents the length of a side of the square.

Let's consider an example. If each side of the square is 4 inches, to find the area, you would square the side length. In this case, that would be 4² = 16. Therefore, the area of this square is 16 square inches.

The symbol for square inches is in², reflecting that we are measuring area or a two-dimensional space. This concept can be extended to any unit of measurement; if we were using feet instead of inches, for example, we would express the area in square feet (ft²).
