Answer:
21 cm
Step-by-step explanation:
The perimeter is the length of the outside of a shape. In this case, we can simply add up all the edges and multiply by .5(the length of one edge).
Horizontal Edges: 22
Vertical Edges: 20
Total: 42
Perimeter = 
Step-by-step explanation:
Principal(P) =$2200
Rate(R) =4%
Time(T)=2 yrs
Simple Interest=PTR/100
I=2200*4*2/100
=$176
Answer:
-38
Step-by-step explanation:
The slope is rise over run. You need to find out how far one point is from the other. To do this, use the equation for slope.

Plug in the points given into the equation and solve for slope (m).

The slope of the line is -38.
Answer:
B. Angle E=43
Step-by-step explanation:
Angles DEF are = to 73 degrees
73-43=30/2=15
15+15+43=73
B. because anything raised to a power besides 1 isnt linear.
