Step-by-step explanation:
Simplify the radical

= 
= 
Square both sides
T² =
( multiply both sides by (g + f) )
T²(g + f) = Ufg ( distribute left side )
T²g + T²f = Ufg ← subtract Ufg from both sides
T²g - Ufg + T²f = 0 ← subtract T²f from both sides
T²g - Ufg = - T²f ← factor out g from each term on the left side
g(T² - Uf) = - T²f ← divide both sides by (T² - Uf)
g = -
= 
For this case we have the following equation:
an = a1 + (n - 1) • d
Where,
a1 = 57
d = 66-57 = 9
For the term number 250 we have:
n = 250
Substituting the values:
a250 = 57 + (250 - 1) * 9
a250 = 2298
Answer:
D.2298
Obtuse angles measure more than 90 degrees, scalene angles have three different side lengths. Would you like for me to include angle measure in the sketch?
Answer: D. 10.5 hours
Step-by-step explanation:
3 days, 3.5 hours each
3.5 * 3 = 10.5 hours
