Answer:
y= 20 m
x= 15 m
z= 22 degree
Step-by-step explanation:
15+x=30 m
x=30-15
x= 15 m
z-18=40
z= 40-18
z= 22m
Answer: 18x^2 + 48x - 50
Step-by-step explanation: In order to determine the area of the rectangle not covered by the turtle pond, we shall calculate the area of the square pond and subtract it from the area of the rectangle.
The area of the square is given as
Area = L x B, where A and B are of equal measurement (sides of a square)
Area = 8 x 8
Area = 64 ft^2
Next we calculate the area of the rectangle which is given as
Area = L x B, where L = 6X + 2 and W = 3X + 7
Area = (6X + 2) (3X +7)
Area = 18X^2 + 42X + 6X + 14
Area = 18X^2 + 48X + 14
We can now subtract the area of the square from the area of the rectangle
That is Area of the shaded region
= 18X^2 48X + 14 - 64
= 18X^2 + 48X - 50
Therefore, the area of the shaded region = 18X^2 + 48X - 50
Number of combinations of 5 women from 7 = 7C5 = 7*6 / 2 = 21
for men its 7C4 = 7*6*5 / 3*2 = 35
Total number of ways = 21*35 = 735
How does your figure look like?
The answer is negative. You subtract 730 from 850
