Answer:
D) 0
Step-by-step explanation:
Remainder is zero as 10 is fully divisible by 2.
<u>Proof</u>:
- 27x^3 + 9x^2 – 3x – 10 = (3x -2) (9x^
2 +9x+5)
<u>Correct choice is</u> D) 0
The commutatice property for addition says a+b=b+a
If it was for subtraction, then it would be a-b=b-a
Take a=7 and b=5
7-5 is not equal to 5-7
2 is not equal to -2
So subtraction is not commutative for whole numbers.
Hope this helps :)
Answer:
GCF= 1
LCM= 1680
Step-by-step explanation:
GCF= Find the prime factorization of 21, 21 = 3 x 7
Find the prime factorization of 80, 80 = 2 x 2 x 2 x 2 x 5
Then multiply the prime factors both numbers have in common
LCM= multiply the two numbers together and ignore all negative signs
