Answer: option a.
Step-by-step explanation:
Given the expression , you need to remember:
The Product of powers property:
The Power of a power property:
And:
Therefore, as the index of the radical is 2, you can rewrite as:
Rewrite this and simplify. Then:
This matches with the option a.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope between (-3, -2) and (1, 0)
Find the equation of the line
with m and the point (1,0)
substitute
step 2
Find the slope between (-2, -1) and (4, 2)
Find the equation of the line
with m and the point (4,2)
substitute
<em>Compare the equation of the two lines</em>
The two lines are parallel, because their slope is the same, but are different lines
therefore
Beatrice's conclusion is incorrect
All of these points are not on the same line, because are different parallel lines
The slope between (-2,-1) and (1,0) is equal to
