5. 2*(7+x) which if you distributed would be 14+2x.
6.x - 8^2 or x-64.
Hope this helped!
X > 6
2x + 4 > 16
2x > 12
x > 6

The volume of a rectangular prism is the product of its length, width, and height.
V = LWH
V = (1.5 ft)(2.5 ft)(8 ft)
V = 30 ft³
The volume of the prism is 30 cubic feet.
#1) D, 95%
#2) B, 34%
Explanation
#1) The mean is 6 and the standard deviation is 0.2. 5.6 is 0.4 away from the mean; 0.4 is 2 standard deviations. 6.4 is 0.4 away from the mean; again, 0.4 is 2 standard deviations.
The empirical rule states that 95% of data will be within 2 standard deviations of the mean, so 95% is our answer.
#2) 6.2 is only 1 standard deviation away from the mean. However, this is only half of the percentage from the empirical rule, since we are only considering numbers larger than the mean. The empirical rule states that 68% of data will fall within 1 standard deviation from the mean, so we have
68/2 = 34%.
