(3a*2*b)*2*
the ** means its an exponent-Remember that an exponent to an exponent is the two exponents multiplied together, and that each factor is raised to the second power.Thus we have 3^2 * a^2^2*
I have never been very good with fractions, nor variables, so this equation is proper Hell for me.
Seventh grade math should not be this way.-First try to keep all terms containing variables on left h

The graph r = 4secx is a ....
ellipse? circle? parabola? hyperbola? line??
no idea. please help! 10 points for best answer.-I am assuming that we have:
r = 4secθ.
Since secθ = 1/cosθ, we see that:

The hypotenuse of a right triangle has length 17 cm. The sum of the legs is 23 cm. What are their lengths?
I dont know how to solve this question...please help!-if you call one leg = x then other leg
I start with:
2(r+n)(r+n-1) + 3(r+n)-1
I end with:
(2n+2r-1)(n+r+1)
Can you please show me the intermediate steps-Let r+n = t
so, ur eqn becomes :
2t(t-1) + 3t - 1
2t^2 - 2t + 3t - 1
2t^2 + t - 1

Find the value of F
C=35
F=unknown-35 = 5/9(F-32)
35 = 5f/9 - 160/9
35 + 160/9 = 5f/9
475/9 = 5f/9
475 = 5f
f = 95-C=5/9 ( F-32)
35= 5/9 (F-32)
35 x 9/5=F - 32
63=F - 32
F=95
Its so hot :P-C = 35
F =
