Why is it a trick question?   

I start all these problems  with 

$$\begin{array}{rll}\\
gradient&=&gradient\\\\
\frac{y-0}{x-4}&=&\frac{-3}{2}\\\\
y&=&\frac{-3}{2}(x-4)\\\\
\end{array}$$

Gino cannot give away all his knowledge in one go mathematician.

It is like treasure - it is more fun when you dig for it.     LOL

Thanks Mathematician :)

Thanks Gino,  

Mathematician, I think it has to be a systematic analysis but getting it organised properly is the tricky bit :)

7L+11B

umm lets see

7,14,28,35,42,49,56,

can't make any of those with 7*8=56

49+11=60    So I can make 60                                   ANSWER IS NOT 60

42+11=53+11=64  can't make any using  7*6

35+11=46+11=57 can't make any using  7*5

28+11=39+11=50+11=61        SO 4*7+3*11=61     ANSWER IS NOT 61

14+4*11=58       so   2*7+4*11=58                         ANSWER IS NOT 58

7+5*11 = 62

So the answer is 59

This is just pythagoras' theorem

the difference in the xes is   $$x_2-x_1$$

The difference in the y's is     $$y_2-y_1$$

You want the hyptotenuse (d)

$$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$$

9 and 3/32 inches = (9+3/32)/12 feet

so if I understand you properly you want  5*(2+(9+3/32)/12 ) feet

you can do this on the site calc on the home page :)

Work = Force * distance

$$\\(-2)^{-2}=\frac{1}{(-2)^2}=\frac{1}{-2*-2}=\frac{1}{4}\\\\
but\\\\
-2^{-2}=-1*2^{-2} = \frac{-1}{(2)^2}=\frac{-1}{2*2}=\frac{-1}{4}\\\\$$
