Answer:
Givens
- The length of the car in her drawing is 6 cm.
- The scale is 3 cm : 2 m.
- Ivan draws with a relation 2 cm : 1 m.
First, we need to find the actual length of the car using Megan's ratio.
If 2 centimeters is equivalent to 1 actual meter of the car, 6 centimeters of drawing would be equal to

Therefore, the car is 4 meters long.
Now, using this information, we can find the length of the scale drawing of Ivan.

Therefore, Ivan's drawing is 8 centimeters long.
I think its 10
Correct me if im wrong
But all u have to do is multiply 2.5 x 4=10
Answer with Step-by-step explanation:
Let a and b are two integers.
We have to show that
if 3\a+b then 3\a-b is false.
In order to prove that given statement is false we prove this with the help of example
Suppose we have two integers a=2 and b=4
if 3\2+4
3\6=2
2-4=-2
But 3 does not divide -2.
Therefore, the given statement is false.
Hence, proved.
