Question: Anyone know how to work this out
Answer: Yes, I do.
Step-by-step explanation:
This is just a way of making a simple linear equation in one variable look like a geometry problem. Because the diagram is a square, you have to know the definition of a square. Applying that, you get an equation. To solve it, you subtract (4x-1) from both sides, and then divide both sides by two.
Answer:
The length of the side is 20 cm.
Step-by-step explanation:
All sides in a square are of equal length so we have the equation:
6x - 1 = 4x + 6
6x - 4x = 6 + 1
2x = 7
x = 3.5
So the length of the side = 6(3.5) - 1
= 21 - 1
= 20 cm. (answer).
We can check this result by substituting in the other expression for a side:
4x + 6 = 4(3.5) + 6
= 14 + 6
= 20 cm.
