We have been given that a rectangle has a height to width ratio of 3:4.5.
Let h be height and w be width of rectangle.
We can set our given information in an equation as:


Now we will substitute h=1 in this equation.



We can see that width of rectangle is 1.5 times height of rectangle.
Our one set of dimensions of rectangle will be: height=1 and width=1.5.
We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.
Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.
Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.
Answer:
Hey there!
I'm sorry, but your friend is right.
It is the difference between -40 and 12, which is 52.
Let me know if this helps :)

Step by Step Explanation:
- Evaluate the power: Any non-zero expression raised to the power of 0 equals 1
- Simplify: Simplify the expression
- Calculate the product: Any expression multiplied by 1 remains the same.
