First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0,
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i.
The three roots are 2+i, 2-i, -1.
Answer:
845
Step-by-step explanation:
Because they are similar triangles you can find the scale factor first.
395/553 is the scale factor
(395/553)*280=200
(395/553)*350=250
200+250+395 = 845
Answer:
Step-by-step explanation:
inland city has the coldest winter and warmest summer.
inland city, since it has a higher median of around 14.5 Celsius while coastal city has around 14 degrees Celsius
I would prefer to live in coastal city, since it has a smaller range of temperatures. Also, it has nice and mild weather: it has warmer winters than inland city, and cooler summers than inland city.
Yes similar polygons are are two polygons with the same shape but not the same size
