Answer:
![(x+10)(x-10)](https://tex.z-dn.net/?f=%28x%2B10%29%28x-10%29)
Step-by-step explanation:
Given : ![x^{2} -100](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-100)
To Find : What are the factors of ![x^{2} -100](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-100)
Solution:
![x^{2} -100](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-100)
Since 100 =![10^{2}](https://tex.z-dn.net/?f=10%5E%7B2%7D)
![x^{2} -10^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-10%5E%7B2%7D)
using property : ![a^{2} -b^{2} =(a+b)(a-b)](https://tex.z-dn.net/?f=a%5E%7B2%7D%20-b%5E%7B2%7D%20%3D%28a%2Bb%29%28a-b%29)
![(x+10)(x-10)](https://tex.z-dn.net/?f=%28x%2B10%29%28x-10%29)
Thus the factors of
are (x+10) and (x-10)
In the first question, is 4. Part of the question?
The answer for this question will be 20 ft
8= 4x2 so 5x4=20ft
Answer:
160in^2
Step-by-step explanation:
Pls choose mine as brainliest.
2 1/7 + 3/7 (3x-5)= - 4
2 1/7 + (9/7)x - 15/7 = - 4
15/7 + (9/7)x - 15/7 = - 4
(9/7)x = - 4
x = - 4 * 7/9 = - 28/9 = - 3 1/9
Answer is - 28/9 or - 3 1/9.
