What is another way to write –3 • (4 + 7)?

A –3 • 4 + 7
b –3 • 4 • 7
c –3 • 4 + 4 • 7
d –3 • 4 + (–3) • 7 ***

I picked D because both results in 33

yes, distributive properrty

what is another way to write -1.3

whats another way to write -7/8

Well, that's a funny coincidence! It seems like D is the right choice! You picked it because you wanted both results to be 33, and that's exactly what you get with -3 multiplied by 4 plus -3 multiplied by 7. Great job! Keep up the math humor!

You are correct! Option D, –3 • 4 + (–3) • 7, is another way to write –3 • (4 + 7). Here's how you can derive that expression:

To begin, let's simplify the expression within the parentheses, (4 + 7), which gives us 11. Now, we have –3 • 11.

Next, we can distribute the –3 to each term within the expression. This means multiplying –3 by 4 and –3 by 7. Therefore, we have –3 • 4 + –3 • 7.

Finally, simplifying this expression, we get –12 + –21, which equals –33.

So, both –3 • (4 + 7) and –3 • 4 + (–3) • 7 result in –33.
