Answer:

AC is four times longer than DF

Step-by-step explanation:

AC is the diameter of the circle E and DE is the radius of the circle E

AC = 2 x DE

DE is the diameter of the circle F and DF is the radius of the circle F

DE = 2 x DF

AC = 2 x DE

AC = 2 x (2 x DF)

AC = 4 x DF

So AC is four times longer than DF

From how it appears, it seems as the answer will be AC is four times longer than DF. If you lined up four DF lines next to AC, it would be congruent

Solve for <br> 3x + 12= -12

oee [108]

Answer:

x = -8

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 12 from both sides:

3x + 12 (-12) = -12 (-12)

3x = -12 - 12

3x = -24

Next, divide 3 from both sides:

(3x)/3 = (-24)/3

x = -24/3

x = -8

x = -8 is your answer.

How are problems like these solved

Flura [38]

the angles on the opposite sides of a quadrilateral touching the circumference adds up to 180 degrees

so,

(21x-2) + (38x +5) = 180

21x+38x −2+5=180

59x+3=180

59x=177

x=3

Is the sequence geometric? if so, identify the common ratio 1/5,2/15,4/45,8/135,16/405,...

Romashka-Z-Leto [24]

So have the sequence: $\frac{1}{5} , \frac{2}{15} , \frac{4}{45} , \frac{8}{135} , \frac{16}{145} ,...$
To check if the sequence is geometric, we are going to find its common ratio; to do it we are going to use the formula: $r= \frac{a_{n} }{a_{n-1}}$
where
$r$ is the common ratio
$a_{n}$ is the current term in the sequence
$a_{n-1}$ is the previous term in the sequence
In other words we are going to divide the current term by the previous term a few times, and we will to check if that ratio is the same:

For $a_{n}= \frac{2}{15}$ and $a_{n-1}= \frac{1}{5}$ :
$r= \frac{ \frac{2}{15} }{ \frac{1}{5} }$
$r= \frac{2}{3}$

For $a_{n}= \frac{4}{45}$ and $a_{n-1}= \frac{2}{15}$ :
$r= \frac{ \frac{4}{45} }{ \frac{2}{15} }$
$r= \frac{2}{3}$

For $a_{n}= \frac{8}{135}$ and $a_{n-1}= \frac{4}{45}$ :
$r= \frac{ \frac{8}{135} }{ \frac{4}{45} }$
$r= \frac{2}{3}$
As you can see, we have a common ratio!

We can conclude that our sequence is a geometric sequence and its common ratio is $\frac{2}{3}$
