who can answer it i will give u ​

Answer 1

step by step answer sent to you if you satisfy mark as a brainlest

Answer 2

Answer:

Ans 7.)

As per the definition provided,

=> calculating sum of diagonals

i) right diagonal = -6, left diagonal = 0

ii) right diagonal = -9 , left diagonal = -9

we can see that in i) sum of both diagnonals is different, so it isnt a magic square.

going on with ii)

=> calculating sum of each row

row1 = -9

row2 = -9

row3 = -9

=> calculating sum of each column

column1 = -9

column2 = -9

column3 = -9

Hence, ii) is magic square.

Ans 8.)

a - (-b) = a+b

iii) a = 75, b = 84

75 -(-84) = 75 + 84

159 = 159

iv) a = 28, b= 11

28 - (-11) = 28 +11

39 = 39
