Answer:
x = 15
Step-by-step explanation:
Bisects means divide in two equal parts.
Therefore, 74/2 = 37
37 = 2x+7
30 = 2x
15 = x
x = 15
Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) = 
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) =
or
⇒
( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is

Collecting like terms,

Since the signs change when its position changes.
