Evaluate each formula. $$\begin{aligned}&P=a+b+c \text { for } a=12.91, b=19, \text { and }\\&c=23.6\end{aligned}$$

The purpose of this problem is to demonstrate that the distributive property works. And so we're gonna substitute negative or positive your 0.19 in for P. And we should expect to get the same result both times. So in the 1st 1 we have the opposite of 0.19 plus 0.72 inside the parentheses less. Add those numbers together and we get 0.91 And so we have negative 0.91 and the other one, we have the opposite of P, which would be the opposite of your 10.19 minus 0.92 Now you can think of minus as plus a negative. So negative 0.19 plus negative 0.72 with the negative 0.91 We did get the same thing both times.

It was even a better i e could you to one and a bit of be equal itude a really far and first thing Want to computer component off the better a a never to be by formula. We get any coaching. I don't be under the no month of it to be. And here first time we need to commune the noble of it. To be here in coaching discredited the three square bliss for square and it could you five. And also, why don't you find adopt Very so we can do it here So I don't be equal to the Jew times three plus one times for give anybody five. Then we can echo Jew on the time again Nico to the 10/5 And it could you too. And therefore we can find a projection on the i under to be it will equal June the component under I on be terms developed, uh, be I would in no amount of it to be therefore getting to the two times the baby tree for over the number baby five. And then we get equal to, uh, 6/5 and 8/5

Everybody. This is Ricky today, working a 45. And we have to solve for the ratio p over Cuba. Right? So the best way to do this is take log. Besides, that brings over our experiments. Get Don't you want Q 2.86? Now we can just divide everything so P over Q. Walk doing 86 walk. Wait, Get that answer ISS about six. So I hope this video for

It was under better I e co 21 for five and a bit of the ICO Jew No minus 21 Jew on the 1st 1 Want to compete will be the component. I'm no better I under that be and by from the agenda in terms be I don't be numbered The normal of it would be so different We need to find a gnome under veritably now And we ico June the square root off the banister square plus one squared plus two square and equal to three Here again which again the component where you, coach I don't be with under one times months to this phone Times one Let's find times to number three the organism months to for 10 therefore again is on the record You that throw off three and you could you far and then we can find a projection out of it that I am one of it to be bi family. We're gonna component under eye on B times the better be over the nominal B and then get echo June, uh, four times the months to one Jew over the number be recruited a three. Then we get equal to the minus 803 and we have no far under three and eight out of three
