(x2-25)÷(x-5) plz help me

saw5 [17]

Answer:

(x + 5)

Step-by-step explanation:

(x² - 25) ÷ (x-5)

=(x² - 5²) ÷ (x-5)

Using the formula a² - b² = (a + b)(a - b) you get

= (x + 5)(x - 5) ÷ (x - 5)

With division you can cut both (x - 5)

So the answer is (x + 5)

Answer:

Overhead Rate for current year=$7 per machine hour

Step-by-step explanation:

Overhead Cost=$700000

Machine Hours Budgeted=100000

In order to calculate the Pinnacle's factory overhead rate for the current year we will consider the following formula:

Overhead rate for the current year=Budgeted overhead cost for the current year/Machne hours budgeted

$Overhead rate for the current year=\frac{700000}{100000}$

Overhead Rate for current year=$7

So Pinnacle plantwide factory overhead rate for the current year is $7 per machine hour.

Find the area of the regular polygon. Round to the nearest tenth.

mojhsa [17]

Given:

Side length = 12 in

To find:

The area of the regular polygon.

Solution:

Number of sides (n) = 6

Let us find the apothem using formula:

$$a=\frac{s}{2 \tan \left(\frac{180^\circ}{n}\right)}$

where s is side length and n is number of sides.

$$a=\frac{12}{2 \tan \left(\frac{180^\circ}{6}\right)}$

$$a=\frac{6}{ \tan (30^\circ)}$

$$a=\frac{6}{ \frac{1}{\sqrt{3} }}$

$$a=6\sqrt{3}$

Area of the regular polygon:

$A=\frac{1}{2}(\text { Perimeter })(\text { apothem })$

$$A=\frac{1}{2}(6 \times 12)(6\sqrt{3} )$

$$A=\frac{1}{2}(72)(6\sqrt{3} )$

$A=216 \sqrt{3}$

$A=374.1$ in²

The area of the regular polygon is 374.1 in².
