Answer:
(x+1) (7x - 4)
Step-by-step explanation:
7x² + 3x - 4
Use the diamond...
7 times -4 equals -28 and 7 plus -4 = 3
Use factor by grouping b/c a does not equal 1
7x² + 7x - 4x - 4
7x(x + 1) -4(x + 1)
(x+1) (7x - 4)
Answer:
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b
Step-by-step explanation:
The domain refers to values for which the expression is defined.
This implies that, the denominators are not equal to zero.
![(\frac{a + b}{b} - \frac{a}{a + b}) \div ( \frac{a + b}{a} - \frac{b}{a + b})](https://tex.z-dn.net/?f=%20%28%5Cfrac%7Ba%20%2B%20b%7D%7Bb%7D%20-%20%20%5Cfrac%7Ba%7D%7Ba%20%2B%20b%7D%29%20%5Cdiv%20%28%20%5Cfrac%7Ba%20%2B%20b%7D%7Ba%7D%20-%20%20%5Cfrac%7Bb%7D%7Ba%20%2B%20b%7D%29)

![\implies \frac{a}{b}](https://tex.z-dn.net/?f=%20%5Cimplies%20%5Cfrac%7Ba%7D%7Bb%7D%20)
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b
Well, that would be $0.17 per crayon with tax. The answer with out tax depends on where they were bought. Tax where I live would be 7%, making the crayons' shelf price $19.60, that would be $0.15 per crayon.
Answer:
b
Step-by-step explanation:
Answer:
The conclusion is invalid.
The required diagram is shown below:
Step-by-step explanation:
Consider the provided statement.
If you Sleepwell, you will have extra energy Therefore, if you don't have extra energy. you are not taking Sleepwell.
From the above statement we can concluded that Sleepwell is the subset of extra energy.
If you don't have extra energy that means you can not be in the set of those taking sleepwell
Therefore, the conclusion is valid.
The required diagram is shown below:
