G(-1) = 1 - 4 + 1 = -2
f(a-2) = 4(a-2)+3 = 4a - 8 + 3 = 4a - 5
g(3) = 3*3 + 4*3 + 1 = 22
g(a-2) = (a-2)^2 + 4(a-2) + 1 = a^2 - 4a + 4 + 4a - 8 + 1 = a^2 - 3

azamat

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Methane: 1 carbon and 4 hydrogens

A sample 92 hydrogen atoms / carbons = ?

total atoms = ?

Process

       

                         1  :  4  ::  x  :  92

       x = number of carbons

                         x = (92 x 1) / 4

                         x = 92 / 4

                        x = 23 carbons

Total atoms = hydrogen atoms + carbon atoms

                    = 92 + 23

                    = 115 atoms
