Answer:
AD = 48
Step-by-step explanation:
C is the midpoint of AD. B is the midpoint of AC. BC = 12.
Let's draw the line segment using the given information.
BC = 12
C is the midpoint AD so C divides the line segment AD into two halves.
B is the midpoint of AC so B divided the line segment AC into two halves.
So, AB = BC
AB = 12
Now let's find AC.
AC = AB + BC
AC = 12 + 12
AC = 24
AD = AC + CD
C divides AD into two halves. So AC = CD = 24
Therefore, AD = AC + CD
AD = 24 + 24
AD = 48

Answer:
Step-by-step explanation:
Cross multiply,
y(x - 8) = x +3
yx - 8y = x + 3
yx - 8y -x = 3
yx - x = 3 + 8y
(y - 1)x = 3 +8y
<h3>Answer: Choice A</h3>
is not the same as
The base of the log is p, while the base of the exponential is b. The two don't match. If it said then it would be a valid statement since the bases are both p.
-----------------
Extra info:
Choice B is a valid statement because Ln is a natural log with base 'e'
Choice C is valid as any square root is really something to the 1/2 power
Choice D is valid for similar reasons mentioned earlier
