i need help on this question

I am assuming that this is 4 times 4 and 3 times 21; if that is the case, then we do the multiplication first

4x4 = 16; 3x21 = 63

Then we multiply those two numbers together 16x63 = 1008

Thank you

You're welcome!

(4x+ 4) + (3x+ 2 + 1)

oh; okay

add like terms... 4x + 3x = 7x; 4 + 2 + 1 = 7

7x + 7

Thanks again and i need help on a few more heres the other one:

(m^{2} – m – 4) + (m – 5)

Same thing, add like terms...

m^2 - 9

Thanks
