Answer:
x = 8
Step-by-step explanation:
By AA similarity, ΔABD ~ ΔCDE. So, corresponding sides are proportional.
AB/BD = CD/DE
x/12 = 4/6
x = 12(4/6)
x = 8
Answer:
-12
Step-by-step explanation:
Given:
The equation of circle is

To find:
The polar form of given circle.
Solution:
We have,

![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)

Subtracting 9 from both sides, we get

We know that,
and
.


and 
We know that, r is radius it cannot be 0. So,


Therefore, the correct option is A.
I also agree with answer C
Sheila Total:: 6x
<span>Sherri Total:: 5(x+10) = 5x+50
</span><span>(a) Write an equation. Let x represent the amount of one of Sheila’s deposits.
6x = 5x+50
</span><span>(b) Solve the equation. Show your work.
x = 50
</span><span>(c) Check your solution. Show your work.
6*50 = 5(50+10)
300 = 5*60
300 = 300</span>
<span>(d) State the solution in complete sentences.
I'll leave that to you.
