1. explain how you can use a strightedge and a compass to construct an angle that is both congruent and adjacent to a given angle. 2. when constructing a perpendicular bisector, why must the compass opening be greater than 1/2 the length of the segment? 3. when constructing an angle bisector, why must the arcs intersect?answer all questions.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
