By what number would you need to dilate the triangle to obtain a triangle with four times as great of an area as the original triangle

Remember that consecutive means right after the other.
In other words, an example would be:
8 + 10
This is because the next even number after 8 is 10. If we were to use 4, we'd do 4 + 6, and so on.
We're looking for two consecutive even numbers that sum up to a number with a 2 in the ones place.

Let's try 0 + 2 (as they sum up to 2).
Considering that 22 (pretend it's positive) is the sum of two consecutive even numbers, it must be in the range of half of that number.
22 / 2 = 11

So let's try the two even numbers close to 11.
10 and 12 have a sum of 2 in the ones place.
10 + 12 = 22

The two consecutive numbers are -10 and -12.

I hope this helps!
