subtract 2x from both sides and add 3 to both sides and divide both sides by 2 to get x=5

5ab  -   10a^2b

Take  out the greatest   common  factor  =  5ab

To  find out what goes into  the  parentheses......just divide  the original terms by this GCF

5ab                 10a^2 b

___    -           _______   =         1  - 2a

5ab                   5ab

So we have

5ab  ( 1  - 2a  )

huh wierd that its 18....

mhm...

Thanks for answering but apparently, the answer is 18...

I am not sure how that is the case as your reasoning makes sense.

My original answer was 8.

9

Soulotion

n<24+4  n=1⋅ 1+1⋅ 4+2⋅ 2=9

hope that helps 

True that

I asked the same question 2 days ago.

lol

and got the same reply!

hmm, i am not sure... the diagonals of a rhombus do not necessarily have to be equal...

I agree, I also think it should be 4. 🤔

28/4 = 7, which is one of the rhombus's sides. since we know PR is 8, PT would be 4, so now we can use Pythagorean Theorem to solve for QT.

7^2 = b^2+4^2

49 = b^2+16

33 = b^2

b = $\sqrt33$

i hope this helped! please correct me if i am wrong:)

Hi fleccy! :P

I think that's Blueclay :P it kinda makes sense that she would say that...

Wouldnt the answer be 4 units? Because PR is 8 and QT is half of PR. Someone correct me if im wrong.

Oops...slight error....corrected  now  !!!

The  3rd  and  the 5th  are irrational

Thanks for the help you guys

nice, CPhill! but when you solved for f(f(x)), did you maybe forget the 1/ part of the function?

and did you maybe do 2x+5 instead of 2x-5? or maybe you just did some simplifying and i didn't follow that, sorry if that is what you did and i just didn't notice ;o

f ( f(x) )    =             1                                         1

                     _______________    =     _________________    =

                     2  (  1/ (2x  -5) ) - 5                2/ (2x  - 5)  - 5 

    2x   - 5                              2x   - 5

______________   =         ________

[ 2 -  5(2x - 5)]                     27  -10x

The  denominator  cannot =  0 

27  -10 x  = 0

27  = 10x

x =  27  /10      is not in the  domain

CORRECTED   !!!!!

can the rest if it be solved?

A)  do not know ....we have no info on rabbits ....only squirrels

arc  OP   has  the length    2pi  (5)   (60  /360)  =  (10/6) pi  =  (5/3)pi

So  the perimeter is

(5/3)  pi     +  5   +  5  =  

10  +  5pi / 3   =    (30 + 5pi)  /  3

Simplifying under  the radical we  have

(x  -3)^2  - (x  -8)^2    =

x^2  - 6x  +  9   - ( x^2  - 16x + 64)   =

x^2   -6x  +   9     -x^2  + 16x   -  64

10x  -  55       since  we  can't  have a  negative  under  the radical, this  must  be  ≥  0

So

10x  - 55  ≥  0

10 x   ≥   55

x  ≥  55/10

x  ≥ 11/2

Triangle EBA  is similar to triangle  DCE

So

BA  / EB  =    CE   /  CD

6 / 4  =   CE  /  6

6 * 6 /  4   =  CE

36 / 4  =  CE  =   9

So   BC  = BE  +  CE  =  4 + 9  =  13

So....the perimeter  is 

2 ( BC  +  BA)   =   2  ( 13  + 6)  = 2 (19)  =   38

3.25 x 6 = 19.5

32.8 - 19.5 = Amount of cloth total used for pants

                  = 13.3

13.3 ÷ 2 = 6.65 

So, she used 6.65m of cloth for each pair of pants.

Hope this helped!

3x^2 + 4x + 12 = 2x^2 + 3x + 11

x^2 + x + 1 = 0

We're going to use vieta's formula. (https://artofproblemsolving.com/wiki/index.php/Vieta%27s_Formulas) 

r^2 + s^2 = (r+s)^2 - 2rs

r^2 + s^2 = (-1)^2 - 2(1)

r^2 + s^2 = 1 - 2

-1

I hope this helped. :))
