Answer:whats the question?
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Given</u>
- DE = 3x + 2, EF = x + 5, DF = 23
<u>As per segment addition postulate</u>
<u>Substituting values:</u>
- 3x + 2 + x + 5 = 23
- 4x + 7 = 23
- 4x = 16
- x = 4
Surface area of a right cone is defined by: SA = πr² + πrl where r is the radius and 'l' is the slant height of the cone.
SA = π(17)² + π(17)(34)
SA = 289π + 578π
SA = 867π cm²
45,65,70 those are the answers
We have that
[(x²+2x+1)/(x-2)]/[(x²-1)/(x²-4)]
we know that
(x²+2x+1)---------> (x+1)²
(x²-1)------> (x+1)*(x-1)
(x²-4)----->(x+2)*(x-2)
so
[(x+1)²/(x-2)]/[(x+1)*(x-1)/(x+2)*(x-2)]
[(x+1)²*(x+2)*(x-2)]/[(x-2)*(x+1)/(x-1)]
[(x+1)*(x+2)]/[(x-2)*(x-1)]
the answer is
[(x+1)*(x+2)]/[(x-2)*(x-1)]
