How would you solve this? x^2 = 169 What does it =?

Show work so we can see how got the answer.

THANK YOU

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2

How to determine whether two known pairs of points are on the same line.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
