(5 + 7x + 6)/2 = 3x + 9
7x + 11 = 6x + 18
7x - 6x = 7
x = 7
EF = 3x + 9
= 3(7) + 9
= 21 + 9
= 30
Range, from -inf to 4
4 >= f(x) > - inf B
Number 10:
All angles in a triangle =180 degrees
so add the first to and subtract that by 180
166 degrees
180-166=14
so x=14 degrees
Combined like terms than subtract with system of equations
