X=-1 is the answer. Hope that helps!
3x-12 = 12x
-12 = 9x
-12/9 = x
x= -4/3
<span>X squared minus 12
x^2 - 12 =0
x^2 = 12
x = 3V3 (V = square root)
or
x = 3.464</span>
5+1.5=6.5 yards
90-28=62 degrees
Imagine a right triangle where the
a=6.5
B=?
C=?
We use SOH-CAH-TOA
Tan(62degrees)=(x/6.5)
=12.2 yards
