I would recomend them as electives, for students who want a higher level of education, not a required course. I do think school should offer more course options at there school, to specialize a students learning exsperience. So yes I think schools should offer these courses...as electives.
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)
Well that's not really a real number...soooo.:)
Explanation: 750/30=25
The area is 30cm by 25cm because they multiply to 750
Volume of a cylinder = πr^2 h = π x (2)^2 x 3 = π x 4 x 3 = 12π = 37.7 cm^3
