12.5 ft is the length of 1 mm
There's nothing here to 'match' it with.
f(x) = x^2 - 3x + 3
f(z^2) = (z^2)^2 - 3z^2 + 3
f(z^2) = z^4 - 3z^2 + 3
<em><u>g(x)</u></em> is only there to confuse you.
Apparently it was successful.
Answer:
-6 33/40
Step-by-step explanation:

Answer:
x=8 or x=-2
Step-by-step explanation:
x²-16=6x
x²-6x-16=0
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
(x-8)(x+2)=0
either,. or.
x-8=0 x+2=0
x=8 x=-2
