Yes they are equivalent because their ratio is 9
81/9= 9
63/7=9
Answer:
D. 
Step-by-step explanation:
Hello!
We can group the first two terms and the last two terms.
<h3>Factor by Grouping</h3>
Factoring by grouping is the process of breaking down larger polynomials to smaller ones to factor. We can then combine like factors.
In the second step, we can see that we can rewrite 
as 
, as both the two terms share a common factor of 
. We can pull out from that expression. Similarly, 
and 
share a common factor of , so we can pull that out.
1+x you can not add them because they are not like terms
Step-by-step explanation:
Let the number be x
2 more than a number = x + 2
First answer is 27
Multiply -3 with -1
Then multiply it to the 3rd power.
2nd answer is 1 / 1296
First add the expoinents
-12 +8 = -4
Then you would need to do the equation
6^-4 x 6^0
And this would equal 1/1296
