Answer:
L = 17 m, W = 12 m
Explanation:
W = (L - 5) m
P = 2(L + W) = 58 m
Substitute W = L - 5 from the first equation into the second equation and get L:
2[L + (L - 5)] = 58
2(2L - 5) = 58
2L - 5 = 58/2 = 29
L = (29 + 5)/2 = 17
Then W = L - 5 = 17 - 5 = 12
Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
