Step-by-step explanation:
5(x-4) + 3x - 9x + 7
First we use the distributive property to remove the parenthesis
5x -20 + 3x - 9x + 7
then we combine the like terms
-x - 13

Step-by-step explanation:
![{ \tt{ {x}^{2} - 2x - 3 = 0}} \\](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20-%203%20%3D%200%7D%7D%20%5C%5C%20)
By completing squares:
![{ \tt{ {x}^{2} - 2x + { (\frac{2}{2} )}^{2} - 3 - {( \frac{2}{2}) }^{2} = 0 }} \\ { \tt{( {x}^{2} - 2x + 1) = 4}} \\ { \tt{(x - 1) {}^{2} = 4 }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%20%7Bx%7D%5E%7B2%7D%20-%202x%20%20%2B%20%20%7B%20%28%5Cfrac%7B2%7D%7B2%7D%20%29%7D%5E%7B2%7D%20%20-%203%20-%20%20%7B%28%20%5Cfrac%7B2%7D%7B2%7D%29%20%7D%5E%7B2%7D%20%20%3D%200%20%7D%7D%20%5C%5C%20%7B%20%5Ctt%7B%28%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20%2B%201%29%20%3D%204%7D%7D%20%5C%5C%20%7B%20%5Ctt%7B%28x%20-%201%29%20%7B%7D%5E%7B2%7D%20%3D%204%20%7D%7D)

The answer is 6.
22 x 2 = 44
56 - 44 = 12
12 / 2 = 6.
The expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4
For Choice A; 2\10 − 1\6
For Choice B; 3\4 − 1 4
For Choice C; 2/3 - 5/12
For Choice D;. 7\8 − 3\12
For Choice D; 1/2 − 1\4
In essence, the expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4
