7:can make 3 bracelets with 4 beads left over
8: 3 groups with 8 left over

Parallel lines have the same slope.
The given line has a slope of 3, therefore, the line parallel to the given line has a slope of 3.
Now, we have the slope of the line and a point that it passes through.
So, we can use the Point-Slope formula:







The additional information needed to prove both triangles are similar are:
A. ∠B ≅ ∠M
C. △ABC was rotated and dilated by a scale factor between 0 and 1
E. ∠C ≅ ∠L
<h3>What are Similar Triangles?</h3>
When a triangle is rotated and dilated by a scale factor, the new triangle formed has the same shape but different size of the original triangle. However, all its corresponding angles remains congruent.
Thus, for triangles ABC and NML to be similar to each other, since we already known each have one congruent right angles, the additional information needed are:
A. ∠B ≅ ∠M
C. △ABC was rotated and dilated by a scale factor between 0 and 1
E. ∠C ≅ ∠L

Answer:
See below
Step-by-step explanation:
- <em>Bi-conditionals are represented by the symbol ↔ or ⇔ </em>
- <em>
p↔q means that p→q and q→p </em>
<u>Bi-conditional statement:</u>
- A rectangle is a square if and only if all four sides of the rectangle have equal length.
<u>
The associated conditional statements are:
</u>
-
a) If all sides of a rectangle are equal then it is a square.
-
b) If a rectangle is a square then all sides have equal length.
