Answer:
[see below]
Step-by-step explanation:
V = s^3
V = (x+4)^3
V = x^3 + 3x^2 * 4 + 3x * 4^2 + 4^3
V = x^3 + 12x^2 + 48x + 64

Answer:
50 + 25 = 75
50 - 25 = 25
The numbers are 50 and 25
Step-by-step explanation:
The sum of two numbers is 25 and their difference is 75. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 25. In other words, x plus y equals 25 and can be written as equation A:
x + y = 75
The difference between x and y is 75. In other words, x minus y equals 75 and can be written as equation B:
x - y = 75
Now solve equation B for x to get the revised equation B:
x - y = 25
x = 25 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 75
25 + y + y = 75
25 + 2y = 75
2y = 50
y = 25
Now we know y is 25. Which means that we can substitute y for 25 in equation A and solve for x:
x + y = 75
x + 25 = 75
X = 50
Therefore,
Sum: 50 + 25 = 75
Difference: 50 - 25 = 25

Answer:
Option D is correct
Step-by-step explanation:
With x < 4 and y < 5:
P = 4x + 3y < 4(4) + 3(5) = 16 + 15 = 31
=> Option D is correct
