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
(4x+ 4) + (3x+ 2 + 1)
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:
(m2 – m – 4) + (m – 5)
Same thing, add like terms...
m^2 - 9
