Evaluate. 47 + 2d, for d = 3

Answers

Final answer:

The problem evaluates the expression 47 + 2d, by substituting d = 3. This results in 47 + 2*3, which simplifies to 47 + 6. The final answer is 53.

Explanation:

This is a simple algebraic problem. The expression you're asked to evaluate is

47 + 2d

and you've been told to substitute

d = 3

. So substituting, we get 47 + 2*(3). The multiplication operation takes precedence according to the order of operations, so next we calculate 2*3 to get 6. Adding this to 47 gives us 53. Therefore, the solution to 47 + 2d, for d = 3, is 53.

Two times two is four (4), if that is what you need. 
You just add that same number to the base when it comes to multiplication. For example, if you had 4x2, then that would be 4 + 4, which is 8. 

Hi there, 2*2 is 4. Multiplication is repeated addition. I hope this helps, have a good day/evening. :)
