Answer:

8. P=10X+16Y+14

9. a^2+8a-10

10. 15v+22w

11. 10c^2+4c

12. z^3-8z^2+5z+23

Step-by-step explanation:

8. P=2(l+w)

P=2((2x+7)+(3x+8y))

P=2(5x+8y+7)

P=10x+16y+14

9. 3a+a^2+5a-10 = a^2+8a-10

10. 8v+8w+7v+14w = 15v+22w

11. 4c^2+6c+6c^2-2c = 10c^2+4c

12. z^3+5z+15+8-8z^2 = z^3-8z^2+5z+23

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?

USPshnik [31]

$\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ 
 \frac{x}{2 \pi } + \frac{1-x}{2} = 0$
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
