C.  [tex] \dfrac{1}{3x + 1} [/tex]

Step-by-step explanation:

[tex] \dfrac{x + 2}{x^3 + 2x^2 - 9x - 18} \div \dfrac{3x + 1}{x^2 - 9} = [/tex]

Factor all polynomials.

[tex] = \dfrac{x + 2}{x^2(x + 2) -9(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

[tex] = \dfrac{x + 2}{(x^2 - 9)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

To divide by a fraction, multiply by its reciprocal.

[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \times \dfrac{(x + 3)(x - 3)}{3x + 1} [/tex]

Cancel out common factors in the numerator and denominator.

[tex] = \dfrac{1}{3x + 1} [/tex]

Answer: 8


22 is to 11 because they are both on the hypotenuse. Since 11 is half of 22, x would be half of 16, 8.

Answer:

I would think it is 8

Step-by-step explanation:

By assuming the triangles are equal to each other in a way that the larger triangle is the smaller triangle's length times 2. For example, one side of the smaller triangle is 11 so times 2 would be the larger triangle's side. So, by dividing 16 by two, you would get 8. Hope this helped and that I did it correctly!

Answer:

its a reflection

Step-by-step explanation:

If it were a rotation, it wouldnt have overlapped.

If it were a translation, It would have been the wrong way up and not overlapping.

When reflected over line x, it will overlap because it stays rigid and does not change shape or size.

7(m+5) = 21

What is it?​

Answers

Answer:

m = -2

Step-by-step explanation:

Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.

The solution of expression is,

m = - 2

We have to give that,

An expression to solve,

7 (m + 5) = 21

Now, simplify the expression as,

7 (m + 5) = 21

Divide both sides by 7,

m + 5 = 21 / 7

m + 5 = 3

Subtract 5 both side,

m = 3 - 5

m = - 2

So, The solution is, m = - 2

Judy makes 2/5 of a beaded necklace on Monday she makes 3/10 of the necklace on Tuesday she makes 1/5 of the necklace on Wednesday what fraction of the necklace has Judy made so far

Answers

Answer: 9/10

Step-by-step explanation:

Fraction of beaded necklace made on Monday = 2/5

Fraction of beaded necklace made on Tuesday = 3/10

Fraction of beaded necklace made on Wednesday = 1/5

Total fraction made would be the addition of the Fractions made from Monday to Wednesday. This would be:

= 2/5 + 3/10 + 1/5

The lowest common multiple of the denominator is 10. Therefore we'll make them have a common denominator.

= 2/5 + 3/10 + 1/5

= 4/10 + 3/10 + 2/10

= 9/10
