The perimeter of a square box is 100 inches. How long is each side?

A=LxW

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?
