8n-3n=n(8-3)=n(5)=5n=5 times n
5 is a factor of 5n so it is evenly divisible by 5
and since n is a natural number, it is the multiplier to make multipules of 5
Answer:
Rectangle A is not a scale drawing.
Rectangle B is a scale drawing.
Step-by-step explanation:
A scale drawing involves ratios.
Rectangle A:
10cm is double the original 5cm giving us a 1 : 2 ratio.
However, 25cm is <em>not</em> double the original 20cm. This means that this rectangle is not to scale of the given rectangle.
Rectangle B:
10cm is double the original 5cm giving us a 1 : 2 ratio once again.
This time however, 40cm is double the original 20cm. This means that this rectangle is a scale drawing of the given rectangle.
