1) When it says more than, then you have to switch it so it will be 7n + 1 instead of 1+7n.
2) Because you then have to subtract by 5 you have to put the 7n + 1 in parentheses so it reads (7n + 1) - 5
3) And then to evaluate you just have to substitute n for 6
4) 7 * 6 = 42; 42+1 = 43; 43-5 = 38
5) The answer to this expression would be 38

Answer:
D
Step-by-step explanation:
3 and 1 eighths of the yard still needs to be mowed.<span />
Think about it this way: which numbers are perfect squares? The square root of 4 is two, the square root of 49 is 7, and the square root of 64 is 8. That only leaves B.
I hope this helps. Let me know if you need a further explanation.
Answer:
11 units
Step-by-step explanation:
According to ruler postulate, if there are two points A with coordinate a
and point B with coordinate b, \
then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.
mathematically it can be represented as
AB = |a-b| or |b-a|
_________________________________________
in the given problem points are -9 and 2
thus distance
distance between –9 and 2 = |-9 -2| = |-11| = 11
absolute value of -11 is 11
alternatively, distance can be calculated as
distance between –9 and 2 = |2 -(-9) | = |2 + 9 | = |-11| = 11
