The sum of all three is 6x^2y + 2xy^2
Answer:
There are 84 men and 16 women in the U.S Senate.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of males and y be the number of females.
Total members = 100
Thus, we can write the equation:

Men in the U.S Senate totaled 4 more than five times the number of woman.
Thus, we can write the equation:

Solving the two equations by substitution method, we have,

Thus, there are 84 men and 16 women in the U.S Senate.
Let the arc is ABC with angle 324 degree, to find the length of that arc follow the steps;
The circumference of the circle E is :C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180
= 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
