Answer:
Perimeter is 8x²y+26x
Area is 52x³y
Step-by-step explanation:
The perimeter is 2W+2L and area is LW
Perimeter:
2(4x²y)+2(13x)
8x²y+26x
Area:
(4x²y)(13x)
52x³y

Answer:  
</h3>
Explanation:
The identity we'll use is cos(-x) = cos(x) for any value of x. 
So cos(-150) = cos(150). 
Then locate the angle 150 on the unit circle. The terminal point is 
The x coordinate of this terminal point is the value of cos(150).
 
        
        
        
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
