When you're simplifying equations, you have to collect the like terms (the similar ones, eg- fractions would be like terms, and so would letters). When you're simplifying, you also have to take note of the operation before the equation. 1) Firstly, collect the like terms of M (M and -4M). As M comes before -4M, you have to add -4M to M. As -4M is a negative, this overwrites the addition, and this becomes M-4M. This then gives you -3M. The same applies to the fractions, as you have -1/6 + 5/6, you have to add 5/6 to -1/6, and this gives you 4/6, or 2/3 simplified. Therefore, you put these together- and this gives you -3M + 4/6, however, you normally have a negative number second, so one this has been rearranged, this gives you 4/6-3m.
2). Same applies to this one, you also have to collect the like terms of W. 2.3W and -3W. You simply have to subtract -3W from 2.3W, and this gives you -0.7W. You now have to collect the numbers, and you have -7 and 8. 8 is a positive, therefore, you have to add 8 to -7, giving you 1. Therefore, when you collect the like terms, this gives you -0.7W+1. As aforementioned, you cannot have a negative first, so one this is rearranged, this gives you 1-0.7W
Answer: i dislike math because they i think its dull. i don't get excited about numbers and formulas the way i get excited about history, science, languages, or other subjects that are easier to personally connect to. i see math as abstract and irrelevant figures that are difficult to understand. and Math is hard because it is a non-intuitive, non-natural activity. Math don't happen by chance only, it only happens with deliberate, focused work. For this you expend a lot of energy and cause a lot of mental strain, you put yourself on an unconfortable condition for hours, days, sometimes weeks to solve a problem.
The correct answer is A) Both methods protect the security of the presentation, but a digital signature has a private and a public aspect. This answer compares both methods but as well provides the main difference between the two of them.
An electronic signature could be any symbol, image or process attached to the document that represents the signer's identity while the password often ends up being forgotten by the signer and most of the time there's no way to recover it.
