Answer:
35cm
Step-by-step explanation:
Given data
Length= 21cm
Width= 28cm
Diagonal= ???
Applying Pythagoras theorem
D^2= L^2+W^2
D^2= 21^2+28^2
D^2= 441+784
D^2= 1225
D= √1225
D= 35cm
Hence the diagonal is 35cm

I think it's a^2 b^2 + 6ab + 9
X=2
So you solve for x by simplifying bath sides of the equation, then all you do is isolate the variables
