Answer:
B. 27
Step-by-step explanation:
Try the answers and see what works. It helps if the equation is written properly.
√(27 -2) = 27 -22
√25 = 5 . . . . . true
None of the other choices gives a rational value for √(x -2).

<em>Comment on the question</em>
As written, the answer is x=25; not on your list. This is how we can tell the question is not written properly.
√25 -2 = 25 -22
5 -2 = 3 . . . . . true
-6(a+8)
= (-6)(a+8)
= (-6)(a)+(-6)(8)
Your final answer would be -6a - 48!

Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
Answer:
These two lines that are running horizontally are parallel lines.
The angle with measure 115 degrees is congruent to angle 2 (by the law of parallel lines).
So, if these two angles are congruent, angle 2 is also 115 degrees.
