Answer:
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary
These are the equations:
2L+2W=58
L=W+5
Now plug in the second one in the first one:
2(W+5)+2W=58
4W+10=58
4W=48
W=12
L=17
Answer:
5
Step-by-step explanation:
-6+5=-1
-1+5=4
4+5=9
9+5=14
