Answer:
where is the questions I don't know
5x² + |x+1| > 0
5x² + x + 1 > 0
x+1 > 0 because it came from absolute
5x² > 0 because it’s squared
When you try a number you should put it in the original equality
5x² + |x+1|
The statement is not always true.
For Example...
The LCM of 6 and 8 is not the product of the two numbers
6*8= 48
48 is not the LEAST common multiple
Multiples of 6 are...
6,12,18,24,30,36,42,48...
Multiples of 8 are....
8,16,24,32,40,48...
The least common multiple is 24 not 48 even though they are both common multiples.
Step-by-step explanation:
ABC = 90
ABC = ABD + DBC
4x + 7x -9 = 90
11 x = 99
x = 9
ABD = 4X = 4×9 = 36
DBC = 7X -9 = 63 -9 = 54
