Answer:

(6x + 1)(x + 9)

Step-by-step explanation:

6x^2 +9 = - 55x

6x^2 + 55x + 9 = 0

55 is a pretty big number compared to either 6 or 9. Not only that, but 6*9 = 54.

So the answer is going to depend on multiply 6x together with 9

(6x + __ ) ( x + 9)

Now what goes were the underline is?

You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.

(6x + 1 )(x + 9) Answer

Answer:

The equation of <em>Z</em> is: $Z=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})$

Step-by-step explanation:

The first child is of age 1 year.

Then the amount invested for the 1-year old is: $Xv^{17}+Yv^{20}$

The second child is of age 3 years.

Then the amount invested for the 3-year old is: $Xv^{15}+Yv^{18}$

The third child is of age 6 years.

Then the amount invested for the 6-year old is: $Xv^{12}+Yv^{15}$

The one-time investment will be:

$Z=Xv^{17}+Yv^{20}+Xv^{15}+Yv^{18}+Xv^{12}+Yv^{15}\\=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})$

Answer:

<h2>6.3inches</h2>

Step-by-step explanation:

$s= \frac{ \alpha }{360} \times 2\pi \: r \\ \alpha = 45 \\ r = 8$

$s= \frac{45}{360} \times 2 \times 3.14 \times 8 \\ s= \frac{1}{8} \times 50.24 \\$

$s= \frac{50.24}{8} \\ s = 6.28$
