The diagram shows that FG = IJ are congruent segments due to the double tickmarks. These are the hypotenuses of the right triangles.
So that takes care of the "H" in "HL".
The L stands for "leg", so we need to have a congruent pair of corresponding legs.
Due to the orientation of the triangles, it's not clear how the corresponding legs match up, but if any of the following is true
- EF = IK
- EF = JK
- EG = IK
- EG = JK
then we'd have enough to use HL.
If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16 3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16 -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24. 24-16=8. 3x12=36 36-8=28 And, You're done!
Part 1: I'm pretty sure B is soluble in water.
Part 2: The data is showing that A isn't soluble at all (probably cause it's solid or a lipid or something) because the amount undissolved stays the same as B changes in solubility.
