3p - 7 + p = 13
3p + p = 13 + 7
4p = 20
p = 20 : 4
p = 5
The formula is L*W*D, right?
So for the cube, since all sides are equal then the Length, Width and Depth would all be 8 unless otherwise specified. 8*8*8=512
The rectangle would be 10*2*3&1/2 or 10*2*3.5=70
I hope this is correct but if you want check my work with a calculator to make sure.

Answer:
We estimate to have 8.33 times the number 6 in 50 trials.
Step-by-step explanation:
Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.
We will estimate the number of times that she spins a 6 as the expected value of this random variable.
Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.
Then , in this case, with n=50 and p=1/6 we expect to have number of times of having a 6, which is 8.33.
<span>The square root of (a * b) is equal to (the square root of a) * (the square root of b)
-32 equals 32 * -1; therefore, the square root of -32 equals the square root of 32 times the square root of -1.
32 equals 16 * 2; the square root of 32 equals ? 16 * ?2 equals 4* ?2
The square root of -1 is i.
Therefore (2? -32) equals 2 * 4 * i * ?2 = 8i?2</span>
