Lemme try k
(x-3)(x+2)
=x^2-3x+2x-6
x^-x-6
x^2-x-30 = 0
(x-6)(x+5) = 0
x-6 =0
x=6
x+5 =0
x=-5
x=6 or x=-5
great I failed
Answer:
In step one, -8 - 2 should result in -10, not -6.
cos 70 = adjacent / hypotenuse
cos 70 = x / 19
multiply each side by 19
19 cos 70 = x
6.498 = x
x = 6.5
It would b rational...hope this helps
