Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x 
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
Answer: 2) 1767.1
Step-by-step explanation:
For a sphere, V=(4
/3)πr^3. A diameter is 2r. Thus the radius of the circle is 7.5 inches. Thus, the volume is about 1767.15.

Answer:
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
if we solve it
10x-2x means 8x and -20+4 means -16...
and other answer are correct.
- 6x+2x=8x 11+5=+16 so....A is correct 8x+16
- 2(4x+8) .... multiply both numbers in bracket by two. 8x+16
- 8(x+2) multiply both numbers in bracket by eight.8x+16
-1.25 is greater because if u can it like this 1.25 1.03 it will still be greater
