All of the equations contain -4 in their range. A) -4 = sqrt(x) - 5 1 = sqrt(x) x = 1; valid B) -4 = sqrt(x) + 5 -9 = sqrt(x) x = 81; valid C) -4 = sqrt(x + 5) 16 = x + 5 x = 11; valid D) -4 = sqrt(x - 5) 16 = x - 5 x = 21 I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
For this case we are going to assume the following: m: whole number greater than zero. n: integer greater than zero. Where, n> m According to these assumptions, the percentage of growth is given by the following formula: Answer: the number of students did grow by:
