Answer:
x = -2
x = -10
Step-by-step explanation:
<u>Step 1 :</u><u> Rearrange</u>
x² + 12x + 20 = 0
<u>Step 2:</u><u> Factorise</u>
(x + 2)(x + 10)
<u>Step 3:</u><u> Find the roots / values of x</u>
Make each bracket equal zero.
(x + 2) = x = -2
(x + 10) = x = -10

Answer:
The height of the flagpole is ![25\ ft\ 4\ in](https://tex.z-dn.net/?f=25%5C%20ft%5C%204%5C%20in)
Step-by-step explanation:
we know that
If two figures are similar, the the ratio of its corresponding sides is proportional
Remember that
![1\ ft=12\ inches](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20inches)
Convert the measures in inches
![3\ ft=3(12)=36\ in](https://tex.z-dn.net/?f=3%5C%20ft%3D3%2812%29%3D36%5C%20in)
![5\ ft\ 4\ in=5(12)+4=64\ in](https://tex.z-dn.net/?f=5%5C%20ft%5C%204%5C%20in%3D5%2812%29%2B4%3D64%5C%20in)
![14\ ft\ 3\ in=14(12)+3=171\ in](https://tex.z-dn.net/?f=14%5C%20ft%5C%203%5C%20in%3D14%2812%29%2B3%3D171%5C%20in)
![\frac{h}{64}=\frac{171}{36}\\ \\h=171*64/36\\ \\h=304\ in](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B64%7D%3D%5Cfrac%7B171%7D%7B36%7D%5C%5C%20%5C%5Ch%3D171%2A64%2F36%5C%5C%20%5C%5Ch%3D304%5C%20in)
Convert inches into (feet + inches)
![h=304\ in=304/12=25.33\ ft=25\ ft\ 4\ in](https://tex.z-dn.net/?f=h%3D304%5C%20in%3D304%2F12%3D25.33%5C%20ft%3D25%5C%20ft%5C%204%5C%20in)
