using algebra, this can be written as 7(2N+2) 14n+14. 14 times the number plus 14.
It is 5n + 14.

First, calculate the sum of 14 and 26, which is 40. Then, multiply that sum by 4: (4 \times 40 = 160). Therefore, 4 times the sum of 14 and 26 is 160.

The carbon isotope with seven neutrons is carbon-14. The atomic number of carbon is 6, which represents the number of protons. The mass number is the sum of protons and neutrons, so for carbon-14, it is 6 (protons) + 7 (neutrons) = 14. Thus, carbon-14 has an atomic number of 6 and a mass number of 14.
It means that some number is having 14 added to it. The sum of 3 and 14, for example is 3 + 14.
How do you write half a number decreased by 8 is equal to the sum of the number and 14
