What is the perimeter of the figure below?

18 + 6π in

Step-by-step explanation:

P = 7 + 7 + 2 + 2πr/2 + 2

= 18 + 2×6π/2

= 18 + 6π in

18+12π in

Step-by-step explanation:

it's perimeter so you add all the sides that make up the shape

7 in+ 7in+2in +2in and the perimeter of the circle without finishing it 2π6=12π

=18 +12π in

x =-.20752

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
