3+4+6=13
2/13 should be the answer. i am not sure

has 2 oxygens for every carbon.

will contribute one of each for every molecule. You then have to have an even multiple of

molecules to not end up with an odd number of oxygens.
So if you take

, you should end up with 2 carbons on the RHS.

then has 4 oxygens. 2 of them are already accounted for, so you just need one

to balance out the reaction.
Answer:
Yes
Step-by-step explanation:
Answer:
Answer is 3
Step-by-step explanation:
Because the Perimeter is true and area is true.
Adding to the solutions and points gotten, we can further say that: Opposite angles of the parallelogram are congruent, by the theorem of Side Angle side (SAS) (i.e angle AEB = CED )
<h3>Meaning of Congruence</h3>
Congruence can be defined as a term used to depict a state of two object being equal, in harmony, and in agreement.
The congruence of a shaped is verified by some laws which they both must satisfy.
In conclusion, the triangle is congruent with the fact stated in the question and the additional fact added above.
