A.) 29
the actual answer is 29.111111, which would not be a remainder of 1.
It 4 the answer is 4 alpeass
Answer: (7x^2+144)/x^2
Step-by-step explanation:
f(h(x))=
f(12/x)=
(12/x)^2+7=
12^2/x^2 + 7=
144/x^2 +7=
144/x^2 +7*x^2/x^2=
144/x^2+7x^2/x^2=(7x^2+144)/x^2
We have that
t²<span> – 81
</span>
we know that
A difference of two perfect squares, <span> (A</span>²<span> - B</span>²)<span> </span><span>can be factored into </span><span> (A+B) • (A-B)
</span> let
A²-------> t²
B²-------> 9²
then
(t² – 9²)------->(t+9)*(t-9)
the answer is
(t+9)*(t-9)
