correct anser is C ; y=-45
If the following are the definitions of the symbols referenced in the question: c = circumference r = radius d = diameter l = length w = width then NONE of the formulas listed in the question is correct. The circumference of a circle is (pi) times d. d is the diameter, (pi) = 3.14156 (rounded)
by transitive property
That is the correct formula for converting degrees Celsius (or Centigrade) to degrees Fahrenheit.
C equals C represents a double bond between two carbon atoms in a molecule. Each carbon atom is sharing two pairs of electrons with the other carbon atom.
You can form a C-C which is a single bond carbon and you can form a C equals C which is a double bond carbon. But if you were to form a triple C bond then the remaining 2 electrons that are located on the other side of the triple bond cannot form a bonding pair.

a = 2b + c then a - 2b = c ie c = a - 2b
There are 5 sigma bonds and 1 pi bond in the molecule H2C=CH2. The sigma bonds are the single bonds between the carbon atoms and hydrogen atoms, and the carbon atoms are connected by a double bond which consists of 1 sigma bond and 1 pi bond.
As the bond order of a C-C bond increases, the C-H bond length generally decreases. This is because an increase in bond order indicates a stronger bond, leading to a reduction in bond length. Conversely, a decrease in bond order would result in longer C-H bond lengths.
No. In terms of bond strength a C-C bond is stronger than a C-N bond.
The balanced chemical equation is: CO2 + C → 2CO
It is a covalent bond.

C-C is a single-bond carbon C=C is a double-bond carbon... soooo.. if you need a triple-bond carbon make the hyphen thrice..
Benzene contains longer C-C bonds compared to ethene. In benzene, the C-C bond length is intermediate between a single bond and a double bond due to resonance, whereas in ethene, the C-C bond is a double bond which is shorter and stronger than a single bond.
