Question

IF A--A-A=20,B-B-B=15,C-C-C=25THENA+B+C=-60 HOW EXPLAIN​

Answer 1

Answer:

Explanation:

f a-a-a=20  b-b-b=15  c-c-c=25  Then a+b+c is given by,

From given, we have,

a - a - a = 20

0 - a = 20

-a = 20

∴ a = - 20

b - b - b = 15

0 - b = 15

-b = 15

∴ b = - 15

c - c - c = 25

0 - c = 25

-c = 25

∴ c = - 25

Now, consider,

a + b + c = -20 + ( -15 ) + ( -25 )

= -20 - 15 - 25

∴ a + b + c = - 60
