Basically there are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26
Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100
Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)
I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.
<span>Point A with coordinates (x,y) rotated 180 degrees around O gives point A' with coordinates (-x,-y).
Hope this helps :D

i think this is the answer for n=-2/a+4
8x3+5=(—x3)+(—x5)
24+40 =(8x3)+(8x5)
64=24+40
64=64
Answer:
16 square inches
16 inches
Step-by-step explanation:
We know the area formula is A = s² and the perimeter formula is P = 4s, where s is the side length.
Here, s = 4, so plug this value into both equations:
A = s²
A = 4² = 16 square inches
P = 4s
P = 4 * 4 = 16 inches
Both blanks are 16.
