Step-by-step explanation:
Solution :-
1)
The two numbers whose sum is 0 is called additive inverse of each other.
Ex :-
7+(-7) = 0
7 is the additive inverse of -7
-7 is the additive inverse of 7
2)
Let the length of the rectangle be b units
The breadth of the rectangle
=> 3 units less than its length
=> b-3 units
Perimeter of a rectangle = 2(l+b) units
=> P = 2(b+b-3) units
=> P = 2(2b-3)
=> P = 4b-6 units
3)
The measure of each exterior angle of a square is 90°
4)
Given that
2 1/5 +(-3 1/2)
=> (11/5)+(-7/2)
=> (11/5)-(7/2)
LCM of 5 and 2 is 10
=> [ (11×2)-(7×5)]/10
=> (22-35)/10
=> -13/10
=> - 1 3/10
The value is -13/10 or -1 3/10
