Multiply out
remember thatn (-) times (+)=(-) so
+3 times -4=-12
-12x=0
the only number that will work is 0 since 0 times anything=0
x=0
Answer:
Angle ABC = 112°
Step-by-step explanation:
THAT IS CORRECT TRUST ME
Answer:
The expression will be
Step-by-step explanation:
We have given expression ![\frac{3x^4}{(-6x)^{-2}}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E4%7D%7B%28-6x%29%5E%7B-2%7D%7D)
This expression can be re written as ![\frac{3x^4}{0.0277x^{-2}}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E4%7D%7B0.0277x%5E%7B-2%7D%7D)
We know the property of exponent that when two function are divided then the power of exponent is subtracted
So ![\frac{3x^4}{0.0277x^{-2}}=108.30x^6](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E4%7D%7B0.0277x%5E%7B-2%7D%7D%3D108.30x%5E6)
So the expression will be
2x+7x= 450
9x= 450
Divide by 9
X=50
100 ml concentrate cuz 2(50)
350 ml water cuz 7(50)
