Question

Verify the following properties when
a = 12 and b = 15.
a. a-(-5) = a + b
C. a +(-a) = -a + a = 0
b. a + (-b) = a - b
d. -b-(-b) = 0​

Answer 1

Answer:

The answers are 27, 0, -3, and 0

Step-by-step explanation:

Using the value of a and b we get,

a) 12-(-15)=12+15

12+15=12+15

27=27

c) 12+(-12)=-12+12=0

12-12=-12+12

0=0

b) 12+(-15)=12-15

12-15=12-15

-3=-3

d)-15-(-15)=0

-15+15=0

0=0
