Answer:
(x+10) and (x-10)
Step-by-step explanation:
The volume of a rectangular box is defined as
Volume = width*height*length
In this case
Volume = 6x^2-600 = 6*(x^2 - 100)
And we also know,
Volume = (6)*height*length
So,
6*(x^2 - 100) = (6)*height*length
This means that
height*length = (x^2 - 100)
height*length = (x+10)*(x-10)
In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is
. So the 16th term of the sequence is -29.
Answer:
44 degrees
Step-by-step explanation:
The angles x + 2 and x are complementary; they sum up to 90 degrees.
Thus, x + 2 + x = 90 degrees, or:
2x = 88, or
x = 44.
The value of x is 44 degrees.
Answer:
(262, 690)
Step-by-step explanation:
Given that :
Mean score = 476
Standard deviation, s = 107
2 standard deviations above and below the mean :
Mean ± 2s
Hence,
2 standard deviations below :
476 - 2(107)
476 - 214 = 262
2 standard deviations above
476 + 2(107)
476 + 214 = 690
