Addition is defined as one of the main basic operation of mathematics. Addition is also defined as the process of adding one of more numbers. For the addition operation, there are many number of properties used. In that, one of the property is known as the commutative property of addition. It states that the change of order does not change the value of addition.
Commutative property of addition is true for all types of numbers including imaginary numbers. So you can pretty much use any numbers ex.2 + 3 = 3 + 2
Simple. Just add/subtract each term. 4n-2n=2n. 8m+7m=15m.
This is very basic stuff.
Answer:
<h2><u>[A] 0</u></h2>
Explanation:
- <u>Lines of symmetry; A line that cuts a shape exactly in half</u>
If you were to put a line of symmetry down and fold the shape in half on that line, both halves would match exactly.
- If you were to put a line of symmetry down on <u>this triangle</u> both sides <u>would not match</u>, therefore there are no lines of symmetry.
<h3><u>There are zero lines of symmetry, therefore your answer is [A] 0</u></h3>
