Answer 1

(7)
Let the other number=x

According to problem

25*x=900

x=900/25

x=36

(10)
Let the no of rows =x

let the no column=x

Total no of seats =x*x

Total no of seats=x2

ATP

x2=676

676 is the perfect square of 26

x=26

No of rows =26

No OK f column =26

please mark as brainliest

Answer 2

Hey user

Here is your answer :-

7. Let the number be x .

so other number is 25x .

Their product is 900 .

x × 25x = 900 .

25x^2 = 900

25x^2 - 900 = 0

( 5x )^2 - ( 30 )^2 = 0

( 5x - 30 )( 5x + 30 ) = 0

( 5x - 30 ) = 0 or. ( 5x + 30 ) = 0

x = 30/5. or. x = - 30/5

x = 6. or. x = - 6

_________________________

Q. 10 If rows are x then columns will be also x .

No. of trees = no. of rows × no. of columns

676 = x × x

x^2 = 676

x = 26. or x = - 26

But negative value cannot possibile

So the nom of rows and columns is 26 .

Thank you .
