Answer:
120
Step-by-step explanation:
the pic was blury but the bigger rectangle seemed to be 10 by 8 so you multiply 10×8=80. the smaller rectangle is 5 by 8 so you multipy 5×8=40. then add 40+80=120
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
Answer: (X) = y => b^y = x
use that equation to get the exponential form
Step-by-step explanation:
Answer: 108°
Step-by-step explanation: just took the test
The variable x represents the base.
x+(x-52)+(x+56)=166
3x+4=166
3x=162
x=54
Final answer: 54 cm
