What would be the denominator after rationalizing 7/(5√3-5√2) Please tell fast

I will mark branliest please fast
Thank you ☺️

25

7 / (5√3-5√2)

= 7 / (5√3-5√2) * (5√3+5√2) / (5√3+5√2)

=7(5√3+5√2) / (5√3)²-(5√2)²

=35√3+35√2 / 75-50

=35√3+35√2 / 25

Thus the denominator of 7/(5√3-5√2) is 25.

Step-by-step explanation:

Please mark me brainliest

Step-by-step explanation:

=> 7/(5√3-5√2) × (5√3+5√2)/(5√3+5√2)

=> 7(5√3+5√2)/75-50

=> (35√3+35√2)/25.

after rationalising the denominator is 25.

hope this helps you.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
