Answer:

<h2>P = 48</h2><h2>A = 144 </h2>

Step-by-step explanation:

The formula of regular polygon with <em>n</em> sides of length <em>b</em> and apothem <em>a</em>:

$A=\dfrac{nba}{2}$

We have:

n = 6

b = 8

a = 6

Substitute:

$A=\dfrac{(6)(8)(6)}{2}=144$

The perimeter:

$P=6b\to P=(6)(8)=48$

Tony has a rectangular yard he would like to fence. He knows the length of his yard is 3x3+4x2−6x and the width of the yard is 2

Step2247 [10]

Answer:

P = 6x³ + 12x² - 18x + 8

Step-by-step explanation:

Given that:

Length = 3x3+4x2−6x

Width = 2x2−3x+4

The length of fencing needed will be :

Perimeter of rectangle (P) = 2( Length + Width)

P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]

P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)

P = 2(3x³ + 6x² - 9x + 4)

P = 6x³ + 12x² - 18x + 8

choose the equation below that represents the line passing through the point (1,-4) with a slope of 1/2

Archy [21]

Well, we can use the form y = mx + b, where m equals the slope and x and y are the coordinate values:
-4 = 1/2(1) + b
b = 9/2
Therefore, the equation of the line is:
y = 1/2x + 9/2

An angle of 90° measures (___) Pi radians.<br><br>An angle of -pi/5 radians measures ____?<br><br>°.

a_sh-v [17]

$\huge \bf༆ Answer ༄$

Conversion from degree to radian ~

$\boxed{ \sf{ \frac{\pi}{180} \times \theta }}$

$\sf \dfrac{\pi}{180 } \times 90$

$\sf \dfrac{\pi}{2} \: \: rad$

Conversion from radians to degree ~

$\boxed{ \sf{ \frac{180}{\pi} \times \theta}}$

$\sf \dfrac{180}{\pi} \times - \dfrac{ \pi}{5}$

$\sf - 36 \degree$
