I don't know how to simplify this question. Is quotient rule necessary?
barxatty [35]

Answer:

The answer to your question is \frac{(x+1)^{2}(x - 23)}{(x-7)^{3}}, because the directions says to give the answer in factor form.

Step-by-step explanation:

                               \frac{3(x+1)^{2}(x-7)^{2}- (x+1)^{3}(2)(x - 7)}{(x - 7)^{4}}

Factor like terms   (x - 7)(x + 1)²

                               \frac{(x - 7)(x + 1)^{2}[3(x - 7) - 2(x + 1)}{(x - 7)^{4}}

Simplify

                              \frac{(x+1)^{2}[3(x - 7) - 2(x+1)]}{(x-7)^{3}}

Expand

                              \frac{(x+1)^{2}[3x - 21 -2x - 2]}{(x - 7)^{3}}

Simplify

                             \frac{(x + 1)^{2}(x - 23)}{(x - 7)^{3}}

Emily's family loves to work together
Evgesh-ka [11]

Answer:

They have <u>18</u> vegetable plants.

Step-by-step explanation:

Given:

Emily's family loves to work together  in the garden.

They have a. preference for flowers as 80% of  their plants are flowers and the rest  are vegetables.

They have 90 plants  in the garden.

Now, to find the number of vegetable plants.

<u><em>Total plants in the garden = 90.</em></u>

80% of the plants are flowers.

So, number of plants which are flowers = 80% of 90.

=\frac{80}{100} \times 90

=\frac{7200}{100}

=72\ plants.

<u><em>The number of flower plants = 72.</em></u>

Total plants = 90 (given)

So, to get the number of vegetable plants we subtract:

90-72=18\ plants.

<u><em>Thus, vegetable plants = 18.</em></u>

Therefore, they have 18 vegetable plants.
