In triangle NLM, point S is the centroid, QS = (3x – 5) cm, and NS = (4x) cm. Triangle N L M has centroid S. Lines are drawn from each point to the midpoint of the opposite side to form line segments N Q, L R, and M P. The length of line segment N S is 4 x and the length of line segment S Q is 3 x minus 5. What is NS? 5 cm 10 cm 20 cm 30 cm

Amountain climber starts a climb at an elevation of 453 feet above sea level at his first rest stop he has climbed 162 feet and by his second rest stop he has climbed another 207 feet its getting late in the day so the climber starts his way down if the climber desends 285 feet how much does he need to ascend or descend to return to the original starting point

In a rectangle klmn, km = 6x + 16 and ln = 49. find the value of x

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
