Answer 2

Sure! Let's expand the expression step by step.

The problem is:

4(6a - 5)

Step 1: Distribute the 4 to both terms inside the parentheses.

So, we take 4 and multiply it by 6a:
4 * 6a = 24a

Step 2: Next, we take 4 and multiply it by -5:
4 * -5 = -20

Step 3: Now we can write down the result by combining both parts we found:
24a + (-20)

Step 4: Since -20 is the same as subtracting 20, we can write it like this:
24a - 20

So the expression 4(6a - 5) simplifies to:

24a - 20

That’s the final answer!

Answer 3

Sure! Here’s a shorter version:

To expand 4(6a - 5):

Step 1: Multiply 4 by 6a:
4 * 6a = 24a

Step 2: Multiply 4 by -5:
4 * -5 = -20

Step 3: Combine the results:
24a - 20

So, 4(6a - 5) = 24a - 20.
