Answer:
p²-14p+49
Step-by-step explanation: To find the area of a square just multiply side x side. So (p-7)(p-7). Use FOIL or double distributive property to get p²-7p-7p+49 then combine the two middle terms to get p²-14p+49
Answer:
Hence the 90% confidence interval estimate of the population mean is 
Step-by-step explanation:
Given that,
Point estimate = sample mean =
= 88.34
sample standard deviation = s = 19.22
sample size = n = 14
Degrees of freedom = df = n - 1 = 13
Critical value =
df = 1.771
Margin of error
Margin of error = E = 9.10
The 90% confidence interval estimate of the population mean is,

The quotient is 63, and the decimal notation im not sure about
The equilateral triangle is 45 feet.
