Which of the expressions are equivalent to the one below? Check all that apply.
3. (2 + 6) + 4.5
A. (6+2): 3+ 4.5
B. 3.2 + 3.6+4.5
O C.3.2 + (6 + 4): 5
D. 5·4+3.(6+2

Substitute the vales for the variables: (3/2)(4/1)-3+(5/3)(3/1) Follow PEMDAS rules. Multiply first. (3/2)(4/1)=12/2 =6 (5/3)(3/1)=15/3=5. So, the expression is now: 6-3+5. Now, add and subtract from left to right. 6-3+5 = 3+5

Step-by-step explanation:sorry if I’m wrong but I’m big brain

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
