A number: n
five times a number: 5n
four less than five times a number: 5n - 4
four less than five times a number equals 11: 5n - 4 = 11
5n - 4 = 11
5n = 15
n = 3
The number is 3.

Answer:
30 inches
Step-by-step explanation:
Assuming the lengths are measured when B lies between A and C on a line, the segment addition theorem applies:
AC = AB +BC
42 = AB + 12 . . . . . fill in the given numbers
30 = AB . . . . . . . . . subtract 12
The length of AB is 30 inches.
Answer:
(See explanation and attachment below for further details)
Step-by-step explanation:
The parabola must satisfy the following conditions:
The expression for the x-intercepts are, respectively:
x = -3
![4 = C\cdot [(-3)^{2} - 2\cdot k\cdot (-3)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B%28-3%29%5E%7B2%7D%20-%202%5Ccdot%20k%5Ccdot%20%28-3%29%2Bk%5E%7B2%7D%5D)
x = 5
![4 = C\cdot [5^{2}-2\cdot k \cdot (5)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B5%5E%7B2%7D-2%5Ccdot%20k%20%5Ccdot%20%285%29%2Bk%5E%7B2%7D%5D)
By equalizing both expressions:
And,
The equation of parabola is:
