Answer:
The value of x will be 8
Step-by-step explanation:
We have given that 
We have to find the value of x
As 
For finding the value of x we have to square both side
On squaring both side
We done squaring both side for easy simplification

So x = 8
So the value of x will be 8
So answer will be 8
Answer:
x = 32/3
Step-by-step explanation:
p(x) = 13
x + 7/3 = 13
x = 13 - 7/3
x = 32/3
The answer would be B. find a relationship between what is given and what must be found.
Hi there!

1/3x = 6
Begin by multiplying both sides by 3 to cancel the fraction:
1/x = 18
Take the reciprocal of both sides:
x = 1/18
Answer:
My payment for the 7th study session will be 78125 dimes.
Step-by-step explanation:
My friend will pay me 5 dimes for helping him study for the first time.
Now, I agree to help him if he multiplies my payment by 5 for each study session.
So, he will pay 25 dimes for the 2nd study session, 125 dimes for the 3rd study session and so on.
Hence, my payment in each study session increases in geometric progression as follows:
5, 25, 125, ........ so on.
So, the 7th term of this series indicates the number of dimes that my friend pays me after the 7th study session.
This is a G.P. series having first term 5 and common ratio 5, then the 7th term will be
Therefore, my payment for the 7th study session will be 78125 dimes. (Answer)
