(B) 5/6 ·13÷4
(C) 5/6 ÷4·13
(D) 5/6 · 13/4
Step-by-step explanation:
Amount of paint per can =
liters.
Number of cans used to paint 4 cars = 13
Total amount of paint used for 4 cars =
liters.
=
liters.
=
liters.
Total amount of paint used for 1 car =
liters.
=
liters.

For this case we have the following quadratic equation:
![x ^ 2-4x + 23 = 0](https://tex.z-dn.net/?f=x%20%5E%202-4x%20%2B%2023%20%3D%200)
The solutions will be given by:
![x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B-b%20%5Cpm%20%5Csqrt%20%7Bb%20%5E%202-4%20%28a%29%20%28c%29%7D%7D%20%7B2a%7D)
Where:
![a = 1\\b = -4\\c = 23](https://tex.z-dn.net/?f=a%20%3D%201%5C%5Cb%20%3D%20-4%5C%5Cc%20%3D%2023)
Substituting the values we have:
![x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (23)}} {2 (1)}\\x = \frac {4 \pm \sqrt {16-92}} {2}\\x = \frac {4 \pm \sqrt {-76}} {2}\\x = \frac {4 \pm \sqrt {76i ^ 2}} {2}\\x = \frac {4 \pmi \sqrt {76}} {2}\\x = \frac {4 \pmi \sqrt {2 ^ 2 * 19}} {2}\\x = \frac {4 \pm2i \sqrt {19}} {2}\\x = 2 \pm i\sqrt {19}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B-%20%28-%204%29%20%5Cpm%20%5Csqrt%20%7B%28-%204%29%20%5E%202-4%20%281%29%20%2823%29%7D%7D%20%7B2%20%281%29%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpm%20%5Csqrt%20%7B16-92%7D%7D%20%7B2%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpm%20%5Csqrt%20%7B-76%7D%7D%20%7B2%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpm%20%5Csqrt%20%7B76i%20%5E%202%7D%7D%20%7B2%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpmi%20%5Csqrt%20%7B76%7D%7D%20%7B2%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpmi%20%5Csqrt%20%7B2%20%5E%202%20%2A%2019%7D%7D%20%7B2%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B4%20%5Cpm2i%20%5Csqrt%20%7B19%7D%7D%20%7B2%7D%5C%5Cx%20%3D%202%20%5Cpm%20i%5Csqrt%20%7B19%7D)
We have two roots:
![x_ {1} = 2-i \sqrt {19}\\x_ {2} = 2 + i \sqrt {19}](https://tex.z-dn.net/?f=x_%20%7B1%7D%20%3D%202-i%20%5Csqrt%20%7B19%7D%5C%5Cx_%20%7B2%7D%20%3D%202%20%2B%20i%20%5Csqrt%20%7B19%7D)
ANswer:
![x_ {1} = 2-i\sqrt {19}\\x_ {2} = 2 + i\sqrt {19}](https://tex.z-dn.net/?f=x_%20%7B1%7D%20%3D%202-i%5Csqrt%20%7B19%7D%5C%5Cx_%20%7B2%7D%20%3D%202%20%2B%20i%5Csqrt%20%7B19%7D)

Answer:
The triple constraint represents the three constraints or inputs which control the project's capacity to produce.
The three components are Budget, time, and scope.
The relationship between them is an interdependent or triangular shape.
Step-by-step explanation:
The triple constraint represents the three constraints or inputs which control the project's capacity to produce. Budget, Scope and Time.
- Budget - The budget describes the estimated cost of the project.
- Time: The time represents the deadline to complete the project.
- Scope: This is simply what needs to be provided.
These 3 components are dependent to each other.
For example, if time is restricted then scope and budget will be affected. similarly.
The relationship between the three is that one of the two other components must decrease while one component increases for the project to succeed as expected.
