For which rational expression is –2 an excluded value of x?

Kipish [7]

Answer:

option a is the answer

Step-by-step explanation:

put the value of x in each expression as x = -2

you'll see that in option a the expression becomes

$\frac{x - 3}{ {x}^{2} - 4} = \frac{ - 2 - 3}{ {( - 2)}^{2} - 4} \\ = \frac{ - 5}{4 - 4} \\ = \frac{ - 5}{0}$

which is not defined. hence -2 is excluded value

A bookcase has two shelves. The top shelf has 10 more than 1/3 the number of books on the bottom shelf. There are 12 books on th

kobusy [5.1K]

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf $s_{t}$ and the bottom shelf $s_{b}$ .

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

$s_{t}=10+\frac{1}{3}s_{b}$ (1)

Then, we are told there are 12 books on the bottom shelf:

$s_{b}=12$ (2)

Substituting (2) in (1):

$s_{t}=10+\frac{1}{3}(12)$ (3)

$s_{t}=10+\frac{12}{3}$ (4)

$s_{t}=14$ (5) This is the number of books on the top shelf

Hence, the correct option is b.
