Find the value of 3a when a=~4.

To find the value of 3a when a is approximately 4, we simply substitute the value of a into the expression:

3a = 3 * 4

Multiplying 3 by 4, we get:

3a = 12

Therefore, when a is approximately 4, 3a is equal to 12.

To find the value of 3a when a is approximately equal to 4, we can simply substitute the value of a into the expression 3a.

So, if a is approximately equal to 4, then 3a is:

3 * 4 = 12

Therefore, the value of 3a when a is approximately equal to 4 is 12.

To find the value of 3a when a is approximately equal to 4, we simply need to multiply 3 by the value of a.

So, if a is approximately equal to 4, then 3a would be equal to 3 multiplied by 4.

To calculate this, you need to multiply the values: 3 × 4 = 12.

Hence, the value of 3a when a is approximately equal to 4 is 12.
