Answer:
Commutative Property of Addition: a + b = b + a
Step-by-step explanation:
The Commutative Property of Addition implies that even on changing the order of addition the final result (i.e. the sum) remains the same.
- Consider the addition of two numbers, say <em>a</em> and <em>b</em>:
a + b = b + a
Suppose <em>a</em> = 5 and <em>b</em> = 6, then:
<em>a</em> + <em>b</em> = 5 + 6 = 11
<em>b</em> + <em>a</em> = 6 + 5 = 11.
Thus, a + b = b + a.
- Consider the addition of three numbers, say <em>a, b</em> and <em>c</em>:
a + b + c= a + c + b = b + a + c = c + a + b
Suppose <em>a</em> = 4, <em>b</em> = 3 and <em>c</em> = 6, then:
a + b + c = 4 + 3 + 6 = 13
a + c + b = 4 + 6 + 3 = 13
b + a + c = 3 + 4 + 6 = 13
c + a + b = 6 + 4 + 3 = 13.
Thus, a + b + c= a + c + b = b + a + c = c + a + b.

Answer:
Step-by-step explanation:
Break down the figure into two shapes.
SHAPE A: The larger one. We can infer the size of the bottom is 6 cm because it's the same size as it's top counterpart. Same goes for the left side, which will have a measure of 7 cm.
SHAPE B: The smaller one. We're going to use the same method as we did with the first one, and infer the lengths of the other sides using the existing ones.
To calculate area, it's length times width.
SHAPE A: Its two side measures are 6 and 7, which equates to 42 cm^2.
SHAPE B: Its two side measures are 2 and 3, which equates to 6 cm^2.
If you add the two, the total area is 44 cm^2.
Assume that the other number is y.
we know that the addition of both number is -9
this means that:
x+y=-9
reorder this equation to seperate the y variable:
y=-9-x
