solve 4^x+2 = 12 for x using the change of base formula log, y = 10
log b

x ≈ -0.208

Step-by-step explanation:

4^(x + 2) = 12

log₄ 4^(x + 2) = log₄ 12

x + 2 = log₄ 12

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

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

x ≈ -0.208

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
