I am really stuck on a couple of these. 2 column proof Given: FH is congruent to GE and angle HFG is congruent to angle EGF Prove: triangle GEH is congruent with triangle FHE.
write a 2 column proof, Given D is the midpoint of AC, E is the midpoint of BC and DE is congruent to EF, prove: DE is parallel to AB and DE = 1/2 AB. answer is 15 steps

The reason the that C has an infinite number of solutions as opposed to the others is because you essentially have 7x +5 = 7x +5 (because you can add the 4x and 3x to make 7x so any answer will work because it will be the same answer on each side no matter what and the other p...
Reiny thank you because I didn't answer Damon's I knew it had to have something to do with 25 being 1/4 of 100 but your explanation of thinking of it as * 1/4 made sense to me so thank you
Why is t= ln(2)/.04 the same as t= 25ln(2)? Please explain it step by step. What rule do you use or how do you change the .04 to the 25?

the number cube question Assuming the die (number cube) is fair, any side is equally probable. Therefore the probability of landing on "1" is 1/6. The key here is that the tosses are independent: The previous tosses have no impact on the result of the next toss. So y...

The chance of having a boy or girl each time is 1/2 so wouldn't you just say 1/2 * 1/2 *1/2 * 1/2 = 1/16 chances of having 2 boys and 2 girls because each of the 4 times it would be 1/2 to have one or the other so it doesn't change just because of what you had previous...
(a) 2D = 13 - 3 (subtract 3 from both sides) then 2D = 10 so divide both sides by 2 and you end up with D = 10/2 10 divided by 2 is 5 so D = 5 (b) 12E - 3= 0 add three to both sides and know you have 12E=3 now divide both sides by 12 and you have E=3/12 Three divided by 12 is ...
I have t = ln(2)/.04 and the book has the answer as 25ln(2) I know these are the same but please show me the steps to go from ln(20)/.04 to 25ln(2) What rules etc. make it so I can do that so I can do it on later problems Thank you
