View attachment 41111 The b part.............

i found the answer u will do it in this way
(a +b )^2 = a ^2 +b^2 +2ab
(6)^2 = a^2 + b^2 +2*7
36= a^2 +b^2 +14
36-14 = 22
a^2 + b^2 = 22
ans is 22
Hope u got it

 

[saif mahmoud]

for the functions
i guess the ans is 1

 

[Ameena Eesa]

i guess the ans is 1

It's 5
