Answer:
12 ft x 25 ft
Step-by-step explanation:
If L is the length and W is the width:
L = 2W + 1
300 = LW
Substitute:
300 = (2W + 1) W
300 = 2W² + W
0 = 2W² + W − 300
0 = (2W + 25) (W − 12)
W = 12
L = 2W + 1
L = 25
The rectangle is 12 feet wide and 25 feet long.

Answer:
3x^5 . 7x^9
3.7.x^5 .x^9
If base is equal when at multiplication we add index
21.x^(5+9)
21 . x^(14)
Step-by-step explanation:
Let X be the iq score of adults. X is normally distributed with mean of 100 and standard deviation of 20.
If all iq scores are converted to z -scores then we will get z scores. And the z score is standard normal variable with mean=0 and standard deviation =1
Hence the mean and standard deviation of of all z scores will be 0 and 1 respectively.
