First and third, second can still be simplified.
He spent 560. Just multiply 70 with 8
The commutative property of addition means we can add two integers in any order. So yes, It would still apply to two negative integers (for example, -2 + -3 and -3 + -2 both equal five)
Answer:
B)
B)
D)
Step-by-step explanation:
1.
The GCF of all the term of the above polynomial is
, hence we take it outside and form a bracket
The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer
2.
The GCF of all the term of the above polynomial is
, hence we take it outside and form a bracket
The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer
