12/16,
6/8,
3/4, and
45/60
are all equivalent to 24/32.
Now that I've listed those four, there are
only an infinite number of others remaining.
50 + (100% of 50) =
50 + 1(50) =
50 + 50 =
100 <===
Answer: hi, im here to help. -b +/- the square route of b spuared - 4ac/2a is the formula, i'd say its option 3
Step-by-step explanation: if we follow the line we wil find that the.
have you read this book on darwin?
Because x,y,z form a geometric sequence, therefore the common ratio is
r = y/x = z/y
That is,
y² = xz (1)
We are given:
x + y + z = 18
Therefore
x + z = 18 - y (2)
Also,
x² + y² + z² = 612
Therefore, from (1), obtain
x² + z² + xz = 612
(x + z)² - xz = 612
From (1) and (2), obtain
(18 - y)² - y² = 612
324 - 36y + y² - y² = 612
-36y = 288
y = -8
Answer: y = -8
