Answer:
see below
Step-by-step explanation:
Add 4 to find the solution:
z ≤ 7
The value 7 is included in the solution set, so there will be a solid dot at that point. Numbers less than 7 are also included in the solution set, so the number line will be shaded to the left of that solid dot.
x^2 = 800. Take the square root of each side.
x = √(800) and -√(800)
(2x2x2)(2x2)
=2x2x2x2x2
=2x2x2x2x2
=32
