X^2+10x-88=8
where is the mistake and what should be done differently?
Answers
Step-by-step explanation:
a) There's a mistake at the third step from the beginning.
b) Instead of adding 25 , Josh added 100. While solving an equation using "Completing Squares Method" , we need to write the L.H.S. in the form of or
, so that in the next step it can be converted into
or
.
c)
Taking -88 to R.H.S. , it's sign changes and becomes +88.
Using "Completing Squares Method" , L.H.S. can be written as :-

. We could say the stock
is performing at which of the following?
A. On par
B. Par equality
C. Below par
D. Above par
Answers
The stock is performing "Below par" since its current value is below the purchase price. The correct answer is option C.
To determine how the stock is performing, we compare the current value of the stock to the purchase price.
Ten weeks ago, Jerry bought the stock at 211/2, which can be written as 211.5. Today, the stock is valued at 203/8, which is equivalent to 203.375.
Comparing the purchase price (211.5) to the current value (203.375), we can see that the stock has decreased in value.
Therefore, the stock is performing "Below par" since its current value is below the purchase price.
Hence, the correct answer is option C.

Answer:
32.45%
Step-by-step explanation:
To find the buying price as a percent of the selling price, we need to calculate the profit margin as a decimal first:
Profit margin = Selling price - Buying price
Profit margin = $59.95 - $40.50
Profit margin = $19.45
Now we can find the percent by dividing the profit margin by the selling price and multiplying by 100:
Percent = (Profit margin ÷ Selling price) x 100
Percent = ($19.45 / $59.95) x 100
Percent = 32.45%
Therefore, the buying price is 32.45% of the selling price.

I know how to do algebra, and I could write how to do it for you. But If I start writing and keep going until I explain to you how to do algebra, do you know what you'd have here ? You'd have an algebra book, just like the one you use in school.
If it were possible to explain algebra in a few paragraphs, or even in a few pages, then that's what you would use in school to learn it, instead of a book. And if it could be explained in a few minutes, or even in a few hours, then teacher would explain it all at the beginning of the year, and then you'd have the rest of the whole year to just practice it and get really good at it.
You use a book, and you spend a whole year learning it, because that's what it takes.
I shall now reveal to you the secret hidden sneaky tricks of how to do algebra:
(If you want to print this and stick it on the refrigerator, you have my full permission.
This method is so good that it even works with a lot of other subjects too.)
-- Go to class every day.
-- As you're sitting down, turn off your cellphone and wrap up your gum.
-- Stay awake in class.
-- Listen to what the teacher is saying. In your mind, make pictures of what it means.
-- When you get a homework assignment, write it down.
-- Make a place at home where you always do your homework. Make it a place where other people aren't running through. While you're there doing homework, turn off the radio and your cellphone, and take the buds out of your ears.
-- On the same day you get the homework assignment, when you're home, sit down in the place where you do your homework, and work ALL of the examples in the assignment. (That may mean that you can't go out that night.)
-- If there's something you just don't get, ask the teacher for a time to sit down together and work on it together until you understand it. That's part of the teacher's job.
If you're building a brick house, and you leave out some bricks near the bottom and keep stacking bricks above the hole, the part above the hole could come crashing down any minute, and there's no way to go back later and try and fill in the hole.
Algebra is exactly like that. Each day or two, in class and in homework, you have to use what you learned in thelast day or two. If there's a hole there, it's awfully tough to build anything on top of it. If you don't understand how to do something, or you blow off a couple of homeworks, there is no way to go back and catch up later.
Follow my method, and algebra is easy !
