Can someone help with this math problem pleaseeee

<h3>Answer: Choice A</h3>
Explanation:
The square root undoes the squaring operation.
Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.
Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.
I'm not sure why your teacher is using plus minus notation when that is not correct. Saying is not true. The result of a square root is simply one value only. If your teacher meant
, then it would be a true statement; however, there's no need to involve negative numbers for this problem.

Answer:
The first set is a solution, the second is not.
Step-by-step explanation:
Testing by filling in the numbers into the equation:
(1, 1.5): x=1, y=1.5
⇒ 1.5 =? · 1 +
⇒ 1.5 =? +
⇒ 1.5 =?
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =? · 12 +
⇒ 4 =? +
⇒ 4 =? ⇒ Incorrect: this is not a solution for the equation
