Michelle is performing the following construction. based on the markings that are present, what construction is she performing?
a bisecting an angle
b bisecting a line segment
c copying a angle
d copying a line segment

B. Bisecting a line segment

You forgot to include the construction, so I'll explain how to bisect a line. There are several steps you must follow in order to get this problem solved. First, suppose we have a line segment as shown in the Figure below. If Michelle want to bisect this line segment, she would need to follow these steps:

1. She should choose one end of line segment and place on it.

2. She has to adjust the a bit longer than half the line segment length

4. Next, she must draw two arcs, one of them above and the other below the line.

5. She need to draw arcs from other end of line, but keeping the same compass width.

6. She should draw a line using a ruler where the arcs cross.

try soting them out first

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
