Answer:
3/x + 2/(x+1) = 3/5x
[3 · 5(x + 1) + 2 · 5x] / 5x(x + 1) = 3(x + 1) / 5x(x + 1)
3 · 5(x + 1) + 2 · 5x = 3(x + 1)
15x + 15 + 10x = 3x + 3
15x + 10x - 3x = -15 + 3
22x = -12
x = -12/22 = -6/11
Answer: 35000π cm.
Step-by-step explanation:
First find circumference
Circumference = 2 × π × radius
Circumference = 2 × π × ( diameter / 2 )
Circumference = 2 × π × ( 35 / 2 )
Circumference = 35 × π cm
Now,
1 revolution = 1 circumference
1000 revolution = 1000 circumference
1000 revolution = 1000 × (35 × π)
1000 revolution = 35000π cm.
Answer: 10
Step-by-step explanation:
Vieta's formulas :
5 - 3i + 5 + 3i = b ⇒ b =10
Now, we have the equation:
x² -10x + 34 = 0

Could you rewrite this question in english so we can understand what is being asked? Thank you!
Step-by-step explanation:
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
