1,49x^2 and 81^6 are perfect squares<span />
Hey there,
5x + 6 = 66
5x = 66 - 6
5x = 60
x = 60 / 5
= 12
Whenever a number crosses a equal sign it changes into its opposite - for example when 5 crosses the equal sign, it become -5.
Hope this helps :))

The formula for the volume of a sphere is
V=4/3πr³
plug in the data we know
V=4/3π6³
V=4/3π*216
V=288pi
V=<span>904.778684234
round to the nearest hundredths
V=904.78cm</span>³
Answer=904.78cm³
