$\log (4x - 1) - \log (x + 2) = \log x$
$\log ( (4x - 1)/(x + 2) ) = \log x$
$(4x - 1)/(x + 2) = x$
$4x - 1 = x(x + 2)$
$4x - 1 = x^2 + 2x$
$0 = x^2 - 2x + 1$
$0 = (x - 1)^2$
⇒ $x = 1$

What is the least common denominator of 3/20 and 8/15?
A.30
B.20
C.5
D.60

Answers

5 since both numbers are divisible by 5 and not by any smaller number

The least common denominator is 5.
This is because all of the other numbers are not divisible by the denominators; they are either greater than one of them or not divisible.

Answer:

B: Not proportional

Step-by-step explanation:

This wouldn't be proportional because for you, you are making 22 heartbeats in 20 seconds and 22-20 is 2. But if you look at your friend, he/she is doing 18 heartbeats in 15 seconds so add 5 so that 23 heartbeats is happening in 20 seconds and 23-20 is 3. If we compare, 3 is not the same as 2 making it not proportional.

Answer:

Not proportional

Step-by-step explanation:

22/20 does not equal 18/15.
