For this case, we must simplify the following expression:
By properties of powers and roots we have to:
It can be written equivalently as:
Then, the previous expression can be written as:
Simplifying we have:
Returning to the radical form we have:
Answer:
Answer: h.
Step-by-step explanation:
450 because you are adding +25
The answer would be option A "Statement: 60 = 3x + 15; Reason: substitution." Remember that substitution means replacing something with something else. In this case you would be replacing variables separating the term and the variable in two different equations to get your answer.
Therefore your answer is indeed option A.
Hope this helps.
