A regular hexagon has sides 2 feet long. What is the exact area of the hexagon? What is the approximate area of the hexagon?

nexus9112 [7]

The formula for the area of a hexagon is

$A=\frac{3\sqrt[]{3}}{2}s^2$

where 's' is the length of one side of the regular hexagon.

The side of our regular hexagon is 2 feet, therefore, its area is

$\begin{gathered} A=\frac{3\sqrt[]{3}}{2}\cdot(2)^2=6\sqrt[]{3} \\ 6\sqrt[]{3}=10.3923048454\ldots\approx10 \end{gathered}$

The exact area of the hexagon is 6√3 ft², which is approximately 10 ft².

Whats the perimiter of the following rectangle? The side says x - 2 and the bottom says 2x + 1

irakobra [83]

Answer:

6x-2

Step-by-step explanation:

The perimeter of a rectangle is found by

P = 2(l+w)

=2( x-2 + 2x+1)

Combine like terms

P = 2(3x-1)

Distribute

P = 6x-2

Find the y value for the point that divides the line segment CD into a ratio of 4:1.

PIT_PIT [208]

Answer:

Y = 2

Step-by-step explanation:

For point (x1,y1) and (x2,y2) on coordinate plane if is divided in ratio of m:n.

Then point of division is given by

(n*x1+m*x2)/ m+n, (n*y1+m*y2)/ m+n

________________________________

Given point

c = (9,6)

d = (5,1)

ratio = 4:1

using the above formula , point of division is

x= (1*9+4*5)/ 4+1 y= (1*6+4*1)/ 4+1

x= (9+20)/ 5 y= (6+4)/ 5

x= 29/ 5 y= 10/ 5 =2

Thus, answer is y = 2
