First you would interpret the sentence into an equation like so:
Then you would solve the equation.
n would equal 9.
Answer:
I know this looks super complicated, but it is 37 students were surveyed. This is because more than one could have said they had brothers or sisters. For example:
In a batch of 10 kids,
- 3 kid could have no siblings
- 2 could have (a) sister(s)
- 2 could have (a) brother(s)
- 3 could have (a) brother(s) and (a) sister(s)
*The ( ) is for if they had 1 or more siblings*
This example isn't as specific, but that could be a reason why you got the answer wrong. If the logical answer is 67, well pff, I say what the heck? I was right. Whoever created this test/assignment is stupid.
I hope this helps!

Answer:wanna hang
Step-by-step explanation:
Your answer would be -3/4n+3/8 because 1/4•-3/1n would be -3/4n and then 1/4•3/2 would be 3/8 so your answer would then be -3/4n+3/8.
49a^2 + 4b^2 + 9c^2 -28ab + 12bc- 42ac
= (7a)^2 + (-2b)^2 + (-3c)^2 + (2*7a*-2b) + (2*-2b*-3c) + (2*-3c*7a)
=(7a - 2b - 3c)^2 (Answer)
