Answer:
X = 8
Step-by-step explanation:
A breakdown of the calculation is attached. I hope you find it helpful, thanks.
first step.
Multiply everything in the brackets by the number outside of the brackets.
then; 2x + 8 = 3x - 6
second step.
Collect the like terms, pronumerals on one side and numbers on one side .
2x - 3x = -6 - 8
-x = -14
therefore divide each side by -1 to make it look good then we end up with
x = 14
that's the answer.
Let two consecutive multiples of 3 be x and (x+3)
A/q,
x * (x+3) = 648
➡ x² + 3x = 648
➡ x² + 3x -648 = 0
➡ x² + 27x - 24x -648 = 0
➡ x ( x + 27 ) -24 ( x +27)
➡ ( x - 24) ( x + 27)
➡ x = 24 and x = -27
so, we take x = 24.
Required multiples of 3
➡ x = 24
➡ x +3 = 24+3 = 27.

those are the prime numbers
It's A that's correct!!!!
6/90/45/30/18/9/2
15: 3/5/15/1
45: 45/1/9/5/15/3/
90: 90/1/9/10/45/2/15/6/3/30/5/18
as you see the top "moves" like
2,4,6,8, and next will be 10
the bottom adds 3 to the previos answer
5,8,11,14, next will be 15
5th card is 10/15
