= 2 ^{(10 + 40+120)}                 n = 10+40+120

G9x) has to cancel the -7x^4    (and the 3x^3)    so g(x) has to be of degree 4

360 = b-d   + b    + b +d    + b + 2d

 360 = 4b + 2d

        = 288+ 2d

d = 36                       Angle D =    b + 2d = 72 + 2(36) = 144 degrees

If the slopes are the same then there are no solutions because theya re parallel and do not cross

Arrange each into y = mx+ b form      where m = slope       find the value of 'a' that make them the same slope

   the first equation is already in y = mx + b form         m = 11

2y-4 = ax +5y+3

3y = -ax -7      

y = - a/3  x   - 7/3       so     -a/3 = 11    solve for 'a'

1a + 2   =   2b + 1    I'll switch to  use x and y

2y  = x+1

y = 1/2x + 1/2

    now solve for integers 

       when x = 3   y = 2    too small

       when x = 5   y = 3  

base 3     21₃ = 7

base 5    12₅  = 7                 7

h(t)=-16t^2 +198

100 = -16t^2 + 198 

-16t^2 + 98 = 0

16t^2 = 98

t^2 = 98/16

t = 2.475  sec
