A parallelogram is a polygon that has opposite side parallel and congruent. If you already know that two of the side lengths is 8 cm and 9 cm, the other two sides will also be 8 cm and 9 cm because it has 2 pairs of congruent sides. 8+8+9+9=34 cm for the perimeter.
Answer:
3.55 x t = 28.40 or 28.40/t = 3.55
Step-by-step explanation:
Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12
The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10
There were originally 10 people on team Alpha.
