We call the ratio between two directly proportional quantities the constant of proportionality. When these two quantities may increase or decrease, the constant proportionality always remains the same
9. Area of a triangle is proportional to height. If the height increases by a factor of 4, then ...
The area will increase by a factor of 4. . . . . (2nd selection)
10. The base lengths and height are needed:
• 5 mm
• 8 mm
• 10 mm
Answer: FALSE.
Step-by-step explanation:
Given the following equation provided in the exercise:

You need to solve for the variable "x".
In order to solve for "x" you can folllow the steps shown below:
1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:

2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:

Therefore, as you can observe, the given equation has no solutions.
