Hello! For this problem we need to make use of two existing logarithmic properties. These are:
1.

is equal to

2.

is equal to

Following the first property, we can simplify the expression to

.
Then, we will use the second property to the term 8w. The final form of the expression would then be
ANSWER: 
(second option)
Step-by-step explanation:
19-4c=17
19-17=4c
2=4c
2/4=c
therefore, c=1/2
Divide both sides by r. Then multiply each side by s.
Your final answer should be r=2(3.14)sh
Answer:

Step-by-step explanation:
we have the triangle GHJ
If the segment side GH is equal to the segment JH
then
The triangle GHJ is an isosceles triangle
Remember that
An isosceles triangle has two equal interior angles and two equal sides
so
m∠G=m∠J
we have
m∠G=(7x+5)°
m∠J=(x+47)°
equate the equations
(7x+5)°=(x+47)°
Solve for x

Answer:
Solution: Option C
Step-by-step explanation:
Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).
(Factor the expression "x² + 8x")
(Factor the expression "y² - 12y")
That leaves us with the expression
, or in other words
. As you can see our solution is option c.
