Answer:
sqrt(ac)
±---------- = b
3c
Step-by-step explanation:
a= 9b^2 c
Divide each side by 9c
a/9c = 9b^2c / 9c
a/9c= b^2
Take the sqrt of each side
±sqrt(a/9c) = sqt(b^2)
Remember that sqrt (xy) = sqrt(x) sqrt(y)
±sqrt(a/c) * 1/ sqrt(9) = b
±sqrt(a) 1
--------- * ------ = b
sqrt(c) 3
Multiply by sqrt(c)/ sqrt(c)
±sqrt(a) sqrt(c)
--------- * ----------- = b
sqrt(c) 3sqrt(c)
±sqrt(ac)
---------- = b
3c
<u>Answer:</u>

<u>We know that:</u>
<u>Work:</u>
- 21 x 2/3 = x
- => 7 x 3 x 2/3 = x
- => 7 x 2 = x
- => 14 = x
Hence, <u>the value of x is 14.</u>
Hoped this helped.
Answer:
The answer is equal to 3/10
Step-by-step explanation:
The values are not very clear
If it's the product of 3/3 and 3/10
Then 3/3 x 3/10
= 9/30
= 3/10
K so its an equation 546 x
over = over
840 100
when u do cross multiplication it will be 840x=546 * 100
x is about 64%

8n+52=12(n+2)
distribute
8n+52 = 12n+24
subtract 8n from each side
52=4n +24
subtract 24 from each side
28 = 4n
divide by 4 on each side
7=n
