(-∞,4). All I did was isolated x, and it says that x has to be less than 4. That means anything before 4 is fair game. Since the problem said that it can't be equal to 4 (as it would have had to have a line under the less than symbol), I used parenthesis on the 4 side as opposed to hard brackets. The <span>∞ always requires parenthesis. </span>
Answer:
n((2n+3)(5n+2x))
Step-by-step explanation:
that is the step by step solution
Let the integers be x-1, x, x+1.
Given,
x -1 + x + x + 1 = 21 + 2(x - 1)
3x = 21 + 2x - 2
x = 19
Hence, the three integers are 18, 19 and 20.
Answer:
-1/2
Step-by-step explanation:
-2 (4 - x) = 12x – 3
-8+2x=12x-3
+8 +8
2x=12x+5
-12x -12x
-10x=5
/-10 /-10
= -1/2
