I think you want to convert (5/12)pi   to degrees

Just multiply  (5/12) * 180   =  75°

Incidentally........(1/8)pi   = 22.5°

2x=6+(-18) 

2x = 6 - 18

2x = -12       divide both sides by 2

x = -6

Hey, calc1........I'm good....how ' bout you....???

[20152016^2]  / ( [ 20152015^2]   + [20152017^2]  - 2 ] )  =

[20152016^2] / ( [ 20152016 - 1]^2 + [ 20152016 + 1]^2 - 2 )  =

[20152016^2] /( 20152016^2 - 2(20152016) + 1 + 20152016^2 + 2(20152016) + 1  - 2 )   =

[20152016^2] / [ 2(20152016^2]  =

1/2

P.S.  - I did NOT "peek" at any other answer before I did mine.....scout's honor  !!!!

Guest is correct.......

With the enlargement, each square inch is 7 * 7  = 49 times as great as it was before the enlargement.

So  .....

35 x 49  = 1715 in^2   = the enlarged surface area

(7.2 x 10^10)/ (9 x 10^5)  =

(7.2 / 9)  x (10^10 / 10^5)  =

0.8 x 10^5  = 

8 x 10^4  =

80,000

There are nine days for the temperature to fall..........so.....

-1.7(9)  + 11.4 = -3.9° C   on Nov 21

Standard form is :

Ax + By = C      subtract Ax   from both sides

By  = -Ax + C          divide both sides by B

y = (-A/B) x + C/B         now (-A/B)  = the slope = m  ......    and  (C/B )   = b = the y intercept .......so we have

y = mx  + b

And this is slope-intercept form 

2(4x + 2)     =    distribute the 2 over the terms in the parentheses

2 * 4x  + 2 * 2  =

8x + 4
