Answer:
x=0.2 to the nearest tenth
Step-by-step explanation:
The given equation is
![5-(58x+19)=(9-48x)*18](https://tex.z-dn.net/?f=5-%2858x%2B19%29%3D%289-48x%29%2A18)
We apply the distributive property to get:
![5-58x-19=9*18-48x*18](https://tex.z-dn.net/?f=5-58x-19%3D9%2A18-48x%2A18)
![5-58x-19=162-864x](https://tex.z-dn.net/?f=5-58x-19%3D162-864x)
We group similar terms to get:
![864x-58x=162+14](https://tex.z-dn.net/?f=864x-58x%3D162%2B14)
![806x=176](https://tex.z-dn.net/?f=806x%3D176)
![x=\frac{176}{806}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B176%7D%7B806%7D)
![x=\frac{88}{403}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B88%7D%7B403%7D)
x=0.2 to the nearest tenth
Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)
= (x + 3)(x - 3)²
Step-by-step explanation:
Answer: A) 35
Step-by-step explanation:
We have the following:
![\sqrt{215 x}](https://tex.z-dn.net/?f=%5Csqrt%7B215%20x%7D)
Now,
is made up of two factors,
and
:
![215=(43)(5)](https://tex.z-dn.net/?f=215%3D%2843%29%285%29)
So, we have to choose a number for x containing a factor of
and or
. In this case, the best option is
:
Hence:
![\sqrt{215 (35)}=\sqrt{(43)(5)(7)(5)}](https://tex.z-dn.net/?f=%5Csqrt%7B215%20%2835%29%7D%3D%5Csqrt%7B%2843%29%285%29%287%29%285%29%7D)
![\sqrt{215 (35)}=\sqrt{(25)(43)(7)}=\sqrt{25} \sqrt{301}](https://tex.z-dn.net/?f=%5Csqrt%7B215%20%2835%29%7D%3D%5Csqrt%7B%2825%29%2843%29%287%29%7D%3D%5Csqrt%7B25%7D%20%5Csqrt%7B301%7D)
Finally:
![\sqrt{215 (35)}=5 \sqrt{301}](https://tex.z-dn.net/?f=%5Csqrt%7B215%20%2835%29%7D%3D5%20%5Csqrt%7B301%7D)
Answer:
its easy just do rise over run. if u know what that is
