Answer:
x = 3 and x = 4
Step-by-step explanation:
3x - 4 + 4x - 8 = x^2
7x -12 = x^2
x^2 - 7x + 12 = 0
(-4)*(-3) = 12 and (-4)+(-3) = -7
(x-3)(x-4) = 0
x - 3 = 0. x = 3
x - 4 = 0. x = 4
The equation representing this situation would be 3 + 2x = c, where c is the total cost.
To find the cost to bring 12 dogs, you will replace the x with the number 12.
3 + 2 x 12 = 27
The cost would be $27.

<h3>Algebraic properties</h3>
There are several algebraic properties in mathematics; each of which have their own applications
Some of these properties are:
- Commutative
- Distributive
- Associative
- Identity
The mathematical expression is given as:
![13 \cdot (20 \cdot 5)](https://tex.z-dn.net/?f=13%20%5Ccdot%20%2820%20%5Ccdot%205%29)
And it is calculated as follows:
![13 \cdot (20 \cdot 5) = 13 \cdot 100](https://tex.z-dn.net/?f=13%20%5Ccdot%20%2820%20%5Ccdot%205%29%20%3D%2013%20%5Ccdot%20100)
![13 \cdot (20 \cdot 5) = 13 00](https://tex.z-dn.net/?f=13%20%5Ccdot%20%2820%20%5Ccdot%205%29%20%3D%2013%2000)
The property applied above is the associative property
