Answer:
7n^2
Step-by-step explanation:
Multiply 8/n by 7n/7n to get 56n/7n^2
√64=8 ∛8=2
In the √, you find something that squares into the number
In the ∛, you find something that cubes into the number
You would divided both sides by 3 and 1x would equal 6
In this question , we have to use compound interest formula, which is

Here Amount after 3 years = $133.10
Rate of interest = 10%=0.1
TIme =3 years
So we get

Now we have principal, P = $100,
Rate of interest, r =0.1
Time, t = 5 years
So we will get

So the balance after 5 years will be $161.05 .
The second answer is right because when you multiply -2 by 7 and -y it should be -14 and 2y
