Question

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

Answer 1

You could expand the brackets by multiplying everything inside the brackets by the number outside the brackets:
-3x4 + (-3)x7
Are you able to simplify this?

Answer 2

I don't understand what you mean. I was given 4 options. *–3 • 4 + 7*
*–3 • 4 • 7*
*–3 • 4 + 4 • 7*
*–3 • 4 + (–3) • 7*

Answer 3

Exactly and I've pretty much written one of those out. x means multiplied, so does \[\cdot\]. Are you able to see which is the answer now?

Answer 4

Yes.
