Hi there! :)
A radical equation is an equation in which a variable (ex. x, y, a, v) is under a radical sign. The only equation that has a variable under a radical (x) is the second option. There is an x next to the 2 under the radical.
I hope this helps, DM me if you have anymore questions. :)

3 but in most cases it is 2 real roots and one root has a multiplicity of 2
Answer:
Alternate Angles are equal
If the square perimeter is 8y, then the square side would be:
square perimeter= 4*side
8y= 4*side
side=2y
The square garden side is 3m shorter than the length of the rectangle garden. The rectangle garden length will be:
rectangle length= square sides +3
rectangle length= 2y+3
rectangle perimeter= 2(rectangle length + rectangle side)
rectangle perimeter= 2(2y+3 + 2y+1)
rectangle perimeter= 2(4y+4)
rectangle perimeter= 8y + 8
The inverse of

is

. (This eliminates B and D)

translates to "if

, then

". This means the answer must be A.
