Step-by-step explanation:
1.Make a line l .
2.Make a perpendicular to this line .
3.Extend the line.
4.Extend compass for 5 cm arc .
5.Place the compass on the line l at the point of perpendicular and make arc on the extended line .
6.Draw line through the point of intersection.
Melissa is represented by variable m.
Josh is represented by variable j.
Chau is represented by variable c.
m+j+c= 148
c=4m
j=m+10
Substitute for c and j for the first equation.
m+(m+10)+4m=148
6m+10=148
6m=138
m=23
Plug the known m value in
j=23+10
j=33
c=4(23)
c=92
Final answer: Melissa=23 messages, Josh=33 messages, Chau=92 messages

Answer:
All squares are rectangles.
Step-by-step explanation:
The requirements for a shape to be qualified as a rectangle are that there must be four sides, two sets or parallel sides, and four right (90 degree) angles. The requirements for a square are that all sides must be equal in length and that there must be four right angles. Since the requirements of a square fit under those of a rectangle, all squares are rectangles.
