Find a polynomial that represents the following.
(a) The outside surface area given by the six sides of the cube
(b) The volume of the cube
(2x + 1)( 2x + 1)( 2x + 1) L * W * H
a) 6 * 2x+1* 2x+1
b) (2x+1)(2x+1)(2x+1)=
(2x+1)(2x+1)
8x^3+8x^2+2x+4x^2+4x+1
Combine like terms
8x^3+12x^2+6x+1

94. Distance to the Moon The moon is about 240,000 miles from Earth.
(a) Write this number in scientific notation.
(b) If a rocket traveled at 4 * 10^4 miles per hour, how long would it take for it to reach the moon?
2.4 X 10^5 miles
b. v = x/t Formula for velocity
vt = x Multiply both sides by t
t = x/v Divide both sides by v
t = (2.4 X 10^5) Substitute in the values of the variables (4 X 10^4) t = 2.4/4 * 10^5/10^4 Group the constants and the powers of ten
t = .6 * 10 Simplify the fractions
t = 6 hours Multiply the remaining power of 10
