plz answer these question it's very urgent​

Answer 1

Step-by-step explanation:

group of teachers(a+b)=10.

group of girls (a^2+b^2)=58.

group of boys (a^3+b^3)=?.

(a) we know that (a+b)^2= [a^2+b^2]+2ab.

here,. (10)^2=58+2ab.

100=58+2ab.

100-58=2ab.

21=ab

now,(a^3+b^3)= (a+b) (a^2+b^2)-2ab)

putting the value,= (10) (58-21)

=(10)37

370 boys
