The sum of a number and its square is 72. what is the number?

Answers


Any equation that has something squared in it always has two solutions.
The equation that you'd use to solve this problem is no exception.

You said that    x² + x = 72

Subtract  72  from each side, and it says      x² + x - 72 = 0

That's the equation to solve, and when you do, the value of 'x'
is the answer to your puzzler.

You can solve the equation using the quadratic formula, or even
by factoring if you can handle it that way.

       (x + 9) (x - 8) = 0

         x = -9
and
         x = 8 .

Sure enough, they both work:

x = -9
x² = 81
x² + x = 81 - 9 = 72

x = 8
x² = 64
x² + x = 64 + 8 = 72

         yay !

Tyler reads 2/15 of a book on Monday 1/3 of it on Tuesday 2/9 of it on wensday,and 3/4 of the remainder on Thursday, if he still has 14 pages left to read on Friday, how many pages are there in the book

Answers

Answer:

129 pages.

Step-by-step explanation:

Let's call the total number of pages.

He reads on Monday. There are 13/15 left.

on Tuesday. There are 2/3 left.

on Wednesday. There are 7/9 left.

Now, the remainder would be the difference between and all pages read at this point

So, 3/4 of this is

The sum of all pages read is

Therefore, there are around 129 pages.

Since Tyler read 3/4 of the remainder, that means 14 pages must be 1/4 of the remainder.

4x14=56 pages

Similarly, 56 pages should be the remainder after he read 2/9 of the book on wednesday.

So, 1-(2/15+1/3+2/9)=14/45

If 56 pages is 14/45 of the whole book,

The book is 180 pages.

Heeeeelpppp!!!! A 45° sector in a circle has an area of 43.2 cm².

What is the area of the circle?

Answers

So remember that a circle has 360 degreesef
45 out of 360 is th fraction that 43.2 is out of the whole circle
45/360=43.2/whole
0.125=43.2/whole
multiply both sides by whole
0.125 times whole=43.2
divide both sides by 0.125
whole=345.6
answer is 345.6 cm^2

Ashley's penny bank is 1/3 full. After she removes 240 pennies, it is 1/9 full. How many pennies can Ashley's bank hold?

Answers

Find change or loss
1/3 to 1/9
make denom 9
1/3 times 3/3=3/9
from 3/9 to 1/9 is change of 2/9

so, 240 was removed
240=2/9 of the bank
times both sides by 9/2
2160/2=18/18 of the bank
1080=bank
can hold 1080 pennies
X = total amount in her bank

1/3x - 240 = 1/9x
1/3x - 1/9x = 240
3/9x - 1/9x = 240
2/9x = 240
x = 240 / (2/9)
x = 240 * 9/2
x = 2160/2
x = 1080
