Step-by-step explanation:
Given the expression
, you need to remember:
The Product of powers property:

The Power of a power property:

And:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
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:
Mrs. Duggin walked a total of
.
Step-by-step explanation:
Given:
Number of miles walked on each day = 
Number of days she walked = 7
We need to find the Total miles she walked using repeated addition method.

Now we know that Repeated Addition means adding each group together and it is also known as Multiplication.
So we can Find Total miles she walked by adding Number of miles walked on each day with number of day times.
OR
we can Find Total miles she walked by Multiplying Number of miles walked on each day with number of days.
framing in equation form we get;
Total miles she walked = 
OR
Total miles she walked = 
Hence Mrs. Duggin walked a total of
.
One tenth of 200 is 1/10 x 200 = 200/10 = 20

Answer:
(-8, 1)
Step-by-step explanation:
x = -2 is a vertical line passing through (-2, 0).
The point (4, 1) is 6 units to the right of this line.
After reflecting the point over the line, the image point will be 6 units to the left of the line: (-8, 1).
