The commutative property of multiplication is ab=ba
so
9(x+5)=(x+5)9
(note, some people on this site like to write x2 for x² but that's not how you math correctly., (x+5)9 doesn't mean (x+5)⁹, it means (x+5) times 9)
In triangle A B C
sides A B and B C are formed an angle ABC or angle B
Answer
angle B
Answer:
The Identity property of addition
Step-by-step explanation:
The identity property of addition states that any number plus zero equals the original number. So, since 0 is being added to 6, it must still be equal to 6. This property works for any number, which is why it works as a property.
This is not to be confused with the identity property of multiplication that states that any number times 1 equals the original number.
Answer:
if the x after the 20 means multiply then the answer is -34/7 or -4 6/7 if the x is a letter then it's 2/11
Step-by-step explanation:
20x2-7x=6
20x2=40
40-7x=6
subtract 40 from 6= 34
-7x=34
34÷-7= -34/7 if needed in a mixed fraction -4 6/7
