A model house that runs completely on renewable energy uses 2windmills and 3solar panels. Each windmill generates M kilowatt-hours (kWh) of energy per year, ad each solar panel generates S kWh per year. Which expressions can we use to describe how many kWh of energy the model house will output in 10years?

good job you smart son of a gun you are smarter that einstein. 7

factor trees are nice.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
