(2x + 4) - (-x + 5)
= (2x + 4) -1(-x + 5)

= 2x + x + 4 - 5
= 3x - 1.
Answer:
40,320 ways
Step-by-step explanation:
From the above question, we know that there are 8 different coloured crayons
They are arranged in 2 rows, with 4 per row.
The number of different ways through which we can arrange the crayons is determined as:
Since each crayons are differently colored, any color can be first and any color can be in a different spot.
Therefore, this is calculated as:
8!
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 40,320 ways.
