If the operation * is defined as a * b = 3a + b, find the value of 3 * 5.

see previous post, same type of question.

2x4

To find the value of 3 * 5, we substitute the values of a and b in the given operation * with the given numbers.

In this case, a = 3 and b = 5.

So, 3 * 5 = 3(3) + 5.

Now, we can simplify this expression by performing the multiplication and addition:

3 * 5 = 9 + 5.

Finally, we can add the numbers together:

3 * 5 = 14.

Therefore, the value of 3 * 5 is 14.
