@asnaseer

Answer 5

15/x:x/25.... cross multiply... and solve....

Answer 6

x² = 15 x 25
x² = 375
im not getting wats x

Answer 7

What are your choices?

Answer 8

@ChiefArnav is it a ratio question or what....?

Answer 9

ratio!

Answer 10

hmmm... if it is a ratio question... then follow my procedure....

Answer 11

? @paki

Answer 12

x=5 sqrt(15),-5 sqrt(15)
OR
x=19.36492, -19.36492

Answer 13

your steps are right.,... just take the root to get rid of the power...

Answer 14

sqrt(375) = 19.36492

Answer 15

x² = 375
or x= 19.36

Answer 16

Got the same. ^

Answer 19

First one.

x=5 sqrt(15),-5 sqrt(15)
OR
x=19.36492, -19.36492

Answer 20

It is the same. :)

Answer 21

i would rather ask my teacher
btw thanks for help nad time

Answer 22

You need the steps?

Answer 23

pleasure.,...

Answer 24

@Blank 
yes i do

Answer 25

Just a second...

Answer 26

(15)/(x)=(x)/(25)

Since there is one rational expression on each side of the equation, this can be solved as a ratio. For example, (A)/(B)=(C)/(D) is equivalent to A*D=B*C.
15*25=x*x

Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
x*x=15*25

Multiply x by x to get x^(2).
x^(2)=15*25

Multiply 15 by 25 to get 375.
x^(2)=375

Take the square root of both sides of the equation to eliminate the exponent on the left-hand side.
x= +- sqrt(375)

Pull all perfect square roots out from under the radical. In this case, remove the 5 because it is a perfect square.
x= +-5 sqrt(15)

First, substitute in the + portion of the +- to find the first solution.
x=5 sqrt(15)

Next, substitute in the - portion of the +- to find the second solution.
x=-5 sqrt(15)

The complete solution is the result of both the + and - portions of the solution.
x=5 sqrt(15),-5 sqrt(15)

Hope this helps. :)
