2a + 4

we know value of [ a = -2 ]

=> -4 + 4

=> 0

Answer 2

GivEn :

• Value of a = -2

To finD:

• Value of 2a + 4 on the given value of a

Solution :

we have given that value of a is -2 and have to find the value of 2a +4 after putting the value of a in it.

Putting the value of a:-

2a +4 ( where a = -2)

=> 2×(-2) +4

=> -4 + 4

=> 0

So the value of 2a +4 on the given value of a is 0.

Hence,

Option D is correct ✅
