The correct factorization would be (5x - 4)(25x^2 + 20x + 16).
The law of factoring cubes states that we use the following formula when we have two cubes being subtracted by one another.
(a - b)(a^2 + ab + b^2)
If we take the cube root of 125x^3 we get 5x, which will be our a value. If we take the cube root of 64, we get 4, which will be our b value. Then we plug in to the formula.
(5x - 4)((5x)^2 + (5x)(4) + 4^2)
(5x - 4)(25x^2 + 20x + 16)
I think the problem with your second answer is that you just did not properly multiply the 5x and the 4 to get 20x (instead you got 15x).

Step-by-step explanation:
50.25
you have to find the area of the pizza first.
to do that you take half of the diameter 16
to get the radius 8
once you have the radius you square it 8*8 = 64
you than multiply it by pie 3.14
and get 200.95 or if you round 201
if you rounded you would get 50.25 if you didn't
than you would get. 50.24
Answer:
The answer to the question is
The percent of the distribution is less than m + d is 84 %
Step-by-step explanation:
To solve the question we list out the variables
Percentage of distribution between m +d and m - d = 68 %
Therefore percentage that are outside the range of m + d and m - d = 32 %
For symmetry to be maintained, of the 32 % that are outside the range of m + d and m - d, 16 % are on either side of the range m + d to m - d
That is 16 % < (m-d) ↔ (m+d)< 16% total range = 100 %
Therefore the proportion of the range lesser than m+d = 100 - 16 or 84 %
