Let the side length of a cube be "s."

volume = s^3

surface area = 6s^2

sum of lengths of edges = 12s

90 = 4x - (2x - 6)

90 = 4x - 2x + 6

84 = 2x

x = 42

Try to set a clear goal for yourself, for example, read 2 or 3 sections of a chapter every day. If you find it hard to focus, use the Pomodoro method. Set a timer for 20 minutes and dedicate all of your focus to reading the chapter. Take a 5 minute break (stretch, go walk, eat a snack) then come back to it.

Rearrange to get slope-intercept form: y = -3x/2 + 6

The slope is -3/2 and the y-intercept is (0, 6).

polygon with 7 sides ==> heptagon

interior angle: 180 * 5/7 = 128 4/7 degrees

exterior angle: 360/7 = 51 3/7 degrees

In general, you should isolate the square roots to one side of the equation, then square both sides.

\(5 \cdot \frac{2}{3} = \boxed{\frac{10}{3}}\)

In multiplication, the result is only as significant as the least accurate term.

75.6 x 12.33 = 932.148 = 932
