To find the value of the expression 5(2 + 3) - 4, we start by simplifying the expression within the parentheses.

First, we calculate the sum inside the parentheses:

2 + 3 = 5.

Next, we substitute this sum back into the expression:

5(5) - 4.

Now, we compute the multiplication:

5 * 5 = 25.

Then, we subtract 4 from this product:

25 - 4 = 21.

Thus, the value of the expression is 21. This confirms that the answer is indeed correct.
