Answer:
thank you!
Step-by-step explanation:
have a good day! :)
The six scores have to average out to the mean, so their sum has to be six times the mean. Since the sum of the first five is 5 more than 5 times the mean, the remaining score must be 5 less than the mean.
Answer: 5 points below the mean
Answer:
side 1=5x^2+103x+40
side2=5x^3-43+100
side 3=A {let}
we have
perimeter of triangle=side 1+ side2 +side3
5x^4+5x^3+5x^2+50x+100=5x^2+103x+40+5x^3-
43+100+A
A=5x⁴+5x³+5x²+50x+100-5x³-5x²-103x-97
A=5x⁴-53x+3 is your answer
