What is the length of segment ns? 1 unit 2 units 4 units 6 units

Answer-

Solution-

As LR = QR, so NR is a median to side LQ

NM = ML, so MQ is a median to side ML

NP = PQ, so PL is a median to side NQ

So, S is the centroid of the ΔNLQ

From the properties of centroid we know that the centroid divides each median in a ratio of 2:1

So applying this,

Therefore,

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
