What is log(21/x2) written in expanded form? log 21−2 log x 2 log x−log 21 2 log 21−log x log x−log 21+2

Step-by-step explanation:

The given logarithmic expression is .

Observe that the expression in the argument is a quotient.

We apply the quotient property. This property is given as follows:

.

When we apply this property, we obtain,

.

Recall that .

We now apply this property to obtain,

.

Therefore the correct answer is A

468

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
