Question

if a + b+ c =0 and c=10 units. then a+b. c will be a)80 b)200 c)-100 d) -40​

Answer 1

Given :-

◆ a+b+c= 0

◆ and c= 10

To find :-

We have to find the value of -

◆[ a+b]× c

Now ,

Solution:-

a+b+c= 0 - - - - - - - -(i)

• It is given that c = 10

• P ut the given value of c in equation.(i)

a+b+10= 0

a+b= 0-10

a+b= (-10)

• Now we have the value of a+b

The find , a+b×c

• (a+b)= -10

• c= 10

=> (-10 )×10

=> -100

So the correct option is c (-100)

Answer 2

Answer:

Since, a+b+c = 0 ------ eq.(i)

And given that , c = 10

By putting the value of c in eq.(i)

a+b+ 10 = 0

now, (a+b) = -10

Then , (a+b)×c = 10x-10

(a+b) × c = -100

so the answer is = (c) -100.
