Answer:
2z+6
Step-by-step explanation:
I think 9 should be added to both sides.
cofficient of x = 6
half of it = 6/2 = 3
square the 3
to give 3 squared = 3*3 9
One way to approach this is to find (g o f)(x) first and then to replace x by -7:
g( f(x) ) = (x^2+6) + 8/(x^2+6)
Now replace x with -7. We get: ( g o f )(-7) = 49+6+8 / (49+6), or
= 55 + 8 / 55, or 55 8/55 (ans.)
W=15
Subtract 80 from both sides then you divide by -2w.
