Answer:

$A.\,\orange{ \bold{ \frac{x - 3}{3x + 1} }}$

Step-by-step explanation:

$\frac{x + 2}{ {x}^{2} + 5x + 6 } \div \frac{3x + 1}{ {x}^{2} - 9} \\ \\ = \frac{x + 2}{ {x}^{2} + 3x + 2x+ 6 } \div \frac{3x + 1}{ {x}^{2} - {(3)}^{2} } \\ \\ = \frac{\cancel{x + 2}}{ \cancel{{({x}+ 3)}} \cancel{(x+ 2) }} \times \frac{\cancel{( {x} + 3)}( {x} - {3)}}{3x + 1} \\ \\ = \purple{ \bold{ \frac{x - 3}{3x + 1} }}$

Negative two and one-fourth divded by negative one and one-half

Bond [772]

Answer:

The answer is 3/2 or 1 1/2

Step-by-step explanation:

First, you have to make it as a improper fraction :

$- 2 \frac{1}{4}$

$= - \frac{( 2 \times 4) + 1}{4}$

$= - \frac{9}{4}$

$- 1 \frac{1}{2}$

$= - \frac{(1 \times 2) + 1}{2}$

$= - \frac{3}{2}$

Next, you can divide it by cutting out the common factor :

$- \frac{9}{4} \div - \frac{3}{2}$

$= - \frac{9}{4} \times - \frac{2}{3}$

$= - \frac{ 3}{2} \times - 1$

$= \frac{3}{2}$

$= 1 \frac{1}{2}$

How can exponents help you find the area of a rectangle if each side length is multiplied by x?

NeX [460]

Exponents can make the problem smaller and look less confusing. If you see a problem with 5*5*5*5*5*5*5*5 then you're going to eventually loose count and will have to keep repeating. But if you put 5 to the 8th power then you know right away just to multiply 5, (8) times,
