Answer:
(1-2b)/126b^2
Step-by-step explanation:
(7b-14b^2)/(42b^2*21b)
factor out the 7b,
[7b(1-2b)]/882b^3
[7b(1-2b)]/[7b(126b^2)]
cancel out the 7b's
(1-2b)/126b^2

Answer:
I think it's an obtuse scalene.
Step-by-step explanation:
The ares of the square is 9 * 9 = 81 m^2
The area of the 4 corners together is pi * r^2 = pi * 4.5^2 = 63.6 m^2
The shaded region is 81 - 63.6 = 17.4 m^2
Answer:
x=27
Step-by-step explanation:
3x -4y =65
Let y=4
3x -4*4 =65
3x-16 = 65
Add 16 to each side
3x-16+16 = 65+16
3x = 81
Divide each side by 3
3x/3 = 81/3
x = 27
