Hi, I need help trying to figure out how to do some math problems. I'm totally confused.

3b - 5 - 2b = 5
b=

x =

5n + 4 - 8n = - 5
n=

36 = 4 (q - 5 )
q =

Here are a few of the examples I have to do. Any step by step help would be appreciated. I have about 30 problems to do. Thanks. so much

My math teacher posed this as a sort of challenge for us. Can anyone help me with it?
Starting from the general equation ax2 + bx +c =0. Come up with the quadratic equation for this equation by completing the square.
Thanks so much for any help!

Can anyone help me? I have a maths textbook but like my classbook it never tells me the method to do the very hard questions. Like all the differentiation questions are f(x)= x^3(x^4+x^6), never a question or example that tells me how to differentiate for example the one below. Your help will be greatly appreciated! Thanks!

f(x) =(x+2)^3 how do you differentiate the equation when it is to ^3?

f(x) = x ^ (3/2) - 8 x ^ (-1/2)
Evaluate f(3) giving the answer in its simplest form with a rational denominator?

How do i evaluate (5 and 4/9) ^ (-1/2)
and find the value of x where (1+x) / x = sqrt 3 giving answer = a+b sqrt 3


Straight line l is perpendicular to line with equation 3x-y=4and passes through the point with co-ords (3,0)
How do i find l? When it is perpendicular do i just put 1 over?

Also how do i find the co-ordinates of the point where l interesect with line y= 2x-13?

A 60.0 kg runner expends 335 W of power while running a marathon. Assuming that 11.0% of the energy is delivered to the muscle tissue and that the excess energy is primarily removed from the body by sweating, determine the volume of bodily fluid (assume it is water) lost per hour in cm^3. (At 37.0°C the latent heat of vaporization of water is 2.41 x 10^6 J/kg.)

Homework is to change this into a 1 step equation. (I can solve)

The base of an isocles triangle is 5 meters less than 4 times the length of a side. The perimeter is 67 meters. Find the length of each side and the base.

I really don't understand this stuff, so if someone could help that would be great.

I was asked to solve this pair of simultanious equations using the substitution method:

2x+y=9
x-2y=7

This is what i did:

Rearrange x-2y=7 to make y the subject:
-2y=7-x
Y=3.5-0.5x

Sub in y:
2x+3.5-0.5x=9
1.5x+3.5=9
1.5x=5.5
X=3 2/3

Sub in x:
3 2/3 -2y=7
-2y=3 1/3
y=1 5/6

Am I right?
