Write the inequality using interval notation and illustrate the inequality using the real number line 1 less than or equals x less than 3 choose the correct interval notation below that represents the inequality.

    1 ≤ 3 - x

x + 1 ≤ 3        added x to both sides

     x ≤ 2        subtracted 1 from both sides

Number line: ←·2    (fill in the dot at 2 since it is "equal to")

Interval Notation: (-∞, 2]

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
