Since the light reflecting off me must travel first off my skin, then to the mirror, then back again.... that's a total of 6ft.... but i'm only 3ft away from the mirror...
Does a mirror duplicate distance?

Hello, we're doing Isoceles triangles and I'm confused. LOL
They are telling us to solve these. Did I do the first one right?
And is there a way I can recheck my answer like in algebra by "backtracking" my answer - is that possible in geometry?


They're telling us Find the value of X

4x-20=3x
4x-20+20=3x+20
4x=3x+20
x=20

the answer I got was: x = 20
is that right?


Im lost with this one.

2.) x° 28°
3.) 3x - 6, x + 10
4) 5x° 2x°
5) 4x + 2, 60°, 6x - 30

Sorry I have no way of putting the triangle pictures in here.
Any help breaking these down to solve x is appreciated!

thanks!

I am making a solution of DL-alpha-Glycerol Phosphate. I want it to be a 25mM solution. The Moleclar Mass is 194.36 (according to the label). I added 1.21 g of Glycerol -PO to 250 mL of water. I think this is the correct amount but the solution looks cloudy and it should be clear. Could someone let me know if I did this wrong?

Could you show me the stepsto solve these problems for quadratic inequalities.

1. (x-2)(x-3)(x-4) >0

(x+1)(x+2)(x+3) _< 0

_< is the arrow on top of the line

The homework question is: for the absolute value 3x-6y less than/equal to 9, is the box in the area defined by the inequality, out of the area, or has both in and out of the area defined by the inequality. The coordinates in the box are[(1,1), (2,1), (2,2), (1,2)].
When I graph the inequality, I get points in and out of the area. I am not sure if this is right. Any help is appreciated. Thanks.
