Rewrite without parentheses and simplify. (u+3)^2

u^2 + 9

Step-by-step explanation:

you would have to put the exponent on the u and 3

so it would by u^2 + 3^2

but simplified it would be

u^2 + 9

we cannot simplify further since we don't know what u equals

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
