Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged

ivanzaharov [21]

The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.

A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.

The dimensions of the original photo is 6 x 6.

Hi,

7x²-2x-8=0, so a = 7, b= - 2, and c = -8.

You just need to apply the formula for square equations:

$x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-2)\pm\sqrt{(-2)^2-4\cdot 7\cdot (-8)}}{2\cdot 7}=\dfrac{2\pm\sqrt{228}}{14}=\dfrac{2\pm\sqrt{4\cdot 57}}{14}=\\\\=\dfrac{1\pm\sqrt{57}}7\Rightarrow x_1=\dfrac{1-\sqrt{57}}7,\;and\;x_2=\dfrac{1+\sqrt{57}}7.$

If a = 2 cm and r = 3.4 cm, find the area of the regular pentagon.

cricket20 [7]

Answer:

$Area = 3.4\ cm^{2}$

Step-by-step explanation:

Assume a pentagon has equal length where a be the side of the pentagon and r be the apothem of the pentagon.

Given:

Sides of pentagon $a=2\ cm$

apothem of pentagon $r=3.4\ cm$

The area of the pentagon formula is given below.

$A = \frac{1}{2}\times bh$

Where b = length of the base or side

And h = height of apothem

Now, we substitute side and apothem length in above formula.

$A = \frac{1}{2}\times 2\times 3.4$

$A = 3.4\ cm^{2}$

Therefore, the area of the pentagon is $3.4\ cm^{2}$
