Tan 40 = h / 20 where h = height of the pole.
h = 20 tan 40 = 16.78 feet
Answer:
<em>x</em> = -33.462
Step-by-step explanation:
-8.58/<em>x</em> = 3.9
<em>x</em> = 3.9 x -8.58
<em>x</em> = -33.462
6x^2-x-2 this is of the form ax^2+bx+c
jk=ac=-12 and j+k=b=-1 so j and k must be -4 and 3 so
6x^2+3x-4x-2
3x(2x+1)-2(2x+1)
(3x-2)(2x+1)
