The coordinates of a point on a coordinate grid are (-2,6). The point is
reflected across the x-axis to obtain a new point. The coordinates of the
reflected point are (4 points)
O (2,6)
O(-2,6)
O (-2,-6)
O 12.-6)

you can't solve x because it is 2 linear equation and you only have one equation

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the answer is $42.96
