The system. only really just possibly. have one solution
Answer:
-27w^9
Step-by-step explanation:
Multiply
-3w^8 × 9w
Step 1:
-3 × 9
= -27
Step 2:
w^8 × w¹
Using the law of indices
w^8 × w¹
= w^(8+1)
= w^9
-3w^8 × 9w
= -27w^9
The first step is correct, because you changed the order of two terms in an addition, and the property is indeed called commutative property of addition.
In the second step, you do the same, but with multiplication: you use . This means that you're using the commutative property again, except for multiplication. So, the answer should be "commutative property of multiplication.
Finally, the third step is correct, because you're distributing the multiplication by 3 to both terms in the parenthesis, and this is called distributive property: it states that
3 because Negative numbers equal less than 0. See the number line attached below. In the number line, all the negative numbers are on the left of the zero and all the positive numbers are on the right of the 0.
