Question

If a+a=60, b+b=40, ab+c=?, find the value of c.

Answer 1

Given That

• a+a=60
• b+b=40

To Find

• ab+c
• value of c

Solution

→a+a=60

→2a=60

→a=60/2

→a=30

→b+b=40

→2b=40

→b=40/2

→b=20

Now ,

• =ab+c
• =30×20+c
• =90+c
• c=-90

Value of ab+c= 30×20-90

Value of ab+c= 90-90

Value of ab+c= 0

Answer 2

Step-by-step explanation:

so value of C is -90
