What is the area of this figure?

Alexxandr [17]

Answer:

The area of the figure is equal to $35\ cm^{2}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of the figure is equal to the area of a square plus the area of a triangle

<u>Find the area of the square</u>

The area of square is equal to

$A=b^{2} =5^{2}=25\ cm^{2}$

<u>Find the area of the triangle</u>

The area of the triangle is equal to

$A=(1/2)bh=(1/2)(5)(4)=10\ cm^{2}$

therefore

The area of the figure is equal to

$25\ cm^{2}+10\ cm^{2}=35\ cm^{2}$

4. Given the perimeter find the missing side.

kakasveta [241]

Answer:

x^2 + 3x + 5

Step-by-step explanation:

sum of the two given side = 2x^3 + 3x^2 + 3x -2

missing side = 2x^3 + 4x^2 + 6x + 3 - 2x^3 - 3x^2 - 3x + 2 = x^2 + 3x + 5

Use the quadratic formula to solve for x.

ryzh [129]

Answer:

The answer is

$x = \frac{ - 9 - \sqrt{41} }{10} \: \: \: , \: \: \: \: \: \frac{ - 9 + \sqrt{41} }{10} \\$

Step-by-step explanation:

5x² + 9x + 2 = 0

Using the quadratic formula that's

$x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} \\$

From the question

a = 5 , b = 9 , c = 2

We have

$x = \frac{ - 9 \pm \sqrt{ {9}^{2} - 4(5)(2) } }{2(5)} \\ = \frac{ - 9 \pm \sqrt{81 -40 } }{10} \\ = \frac{ - 9 \pm \sqrt{41} }{10} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$x = \frac{ - 9 - \sqrt{41} }{10} \: \: \: , \: \: \: \: \: \frac{ - 9 + \sqrt{41} }{10} \\$

Hope this helps you
