x³ + 27 which can be written as x³ + 3³
It is in the form of a³ + b³ = ( a + b) ( a² - ab + b²)
so
x³ + 3³
= (x+ 3) (x² - x * 3 + 3²)
= ( x + 3 ) ( x² - 3x + 9)
Hope this helps you.
From the figure, segment QP is in the ray RP and RP contains N and Q in between
so from the options, the two rays will be : ray QP and ray NP
For SU :
segment SU is in the ray RU and RU contains S and T in between,
so from the options again, the two rays will be : ray RU and ray SU

350*15 is 5250. That is the total words needed to reach her assignment paper goal. Since there are 60 minutes in an hour we would need to figure out how many words she can type per hour. 60*70 is 4200. Then we divide 5250 by 4200. We get 1.25. Soooo our final answer would be 1 hour and 15 minutes need to be set aside to type her assignment. I really hope this is correct it makes sense to me. If not i am truly sorry.
