Answer:
C. 101 - 5(n - 1)
Step-by-step explanation:
d = (26 - 71)/(16 - 7)
d = -45/9
d = -5
a7 = a1 + (7-1)(-5)
71 = a1 - 30
a1 = 101
an = 101 + (n - 1)(-5)
an = 101 - 5(n - 1)
The answer is A. "e" represents a line. When using points represent line, you only need 2. When using points represent plane, you need three but they can't on the same line. And "D" represents a plane.
That’s not the full question but if it was it would be greater bc 10 - 10=0 but 10-10+15 would equal 15 instead of 10
Answer:
A) None
Step-by-step explanation:
1) 
shoudnt neccesarily be a factor of nst, for example, if s = 3, t = 4, and n = 12, then both s and t are factors of n, but 
is not a factor of nst = 144.
2) 
shoudnt neccesarily be a factor of nst. Let s be 4, let t be 6, and let n be 12. Then n is a factor of both s and t, but 
is not a factor of nst = 12*24. In fact, it is a greater number.
3) Again, s+t isnt necessarily a factor of nst, let s be 2 and t be 3. Then both s and t are factor of n = 12. However 5 = s+t is not a factor of nst = 72.
So, neither of the three options is guaranteed to be a factor of nst. In fact, for s = 4, t = 6, and n = 12, none of the three options are valid.
Answer:
-7√5
Step-by-step explanation:
I'll transcribe your verbal question into a symbolic one as best I can:
-2√20 - √125
Note how √20 = √4*√5 and √125 = √25 *√5. Thus,
your -2√20 - √125, after we've factored √5 out of both terms, becomes
-2(2)√5 - 5√5, or -2√5 - 5√5, which combines to form
-7√5 (answer)
