Answer:
Its equal to 1
Step-by-step explanation:
The answer to fill in the blank should be ''Linear''.
If their perimeters are equal, we can add up all the side lengths of each triangle, and set the perimeters equal to each other to find the value of x that satisfies the equation:
x - 2 + x + 3x + 1 = 2x - 5 + x + 4 + 6x - 7
Combine like terms:
5x - 1 = 9x - 8
And finally, solve for x:
7 = 4x
x = 
Therefore, x is equal to
.

"commutative property" in addition and multiplication means that you can exchange the places of integers in addition and multiplication and still get the same answer.
For this question:
10 + 8 = 18 can be rewritten using commutative property as: 8 + 10 = 18
