Answer:
x either equals to 4 of 9 so you can write it like x=4, 9
Step-by-step explanation:
Start by simplifying each sides of the equation.
x^2-13x+36=0
Then factor the left side of the equation.
(x-4)(x-9)=0
Set factors equal to 0
x-4=0 or x-9=0
x=4 or x=9
Answer:6
Step-by-step explanation:
5.670 rounded to whole gram is 6
Answer:
The square root is 1.90
Step-by-step explanation:
Given
![x = \sqrt{3.6}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B3.6%7D)
Required
Find x
Express 3.6 as 36/10
So, we have:
![x = \frac{\sqrt{36}}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B%5Csqrt%7B36%7D%7D%7B%5Csqrt%7B10%7D%7D)
This gives
![x = \frac{6}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7B%5Csqrt%7B10%7D%7D)
Rationalize
![x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7B%5Csqrt%7B10%7D%7D%2A%5Cfrac%7B%5Csqrt%7B10%7D%7D%7B%5Csqrt%7B10%7D%7D)
![x = \frac{6\sqrt{10}}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%5Csqrt%7B10%7D%7D%7B10%7D)
Using a calculator
![\sqrt{10} \approx 3.16](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D%20%5Capprox%203.16)
So, we have:
![x = \frac{6*3.16}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%2A3.16%7D%7B10%7D)
![x = \frac{18.96}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B18.96%7D%7B10%7D)
![x = 1.896](https://tex.z-dn.net/?f=x%20%3D%201.896)
Approximate
![x = 1.90](https://tex.z-dn.net/?f=x%20%3D%201.90)
