Answer:
the answer is (a+2)(a²+5)
thank you
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.
Hope this helps!
Answer:
A. and D.
Step-by-step explanation:
To get the unit rate, you divide the y value by the x value.
180/15 = 12
The x value becomes a 1.
This means A. is correct.
Take the unit rate to find the profit for 20 scarves. To get 20, you multiply 1 by 20.
1 * 20 = 20
Do the same to 12.
12 * 20 = 240
This will give you the point (20, 240).
This means D. is correct.
