Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.
Step-by-step explanation:
P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.
P = 5+20x
=5+20x•5
= 105
The first mill charges $105 For a 5 meter beam while the second beam charges $110

Answer:
(3x + 2)(x-4)
Step-by-step explanation:
3x² - 10x - 8 = 0
(splitting the middle term)
3x² -12x + 2x -8 = 0
3x(x-4) + 2(x-4) = 0
(3x + 2)(x-4) = 0
(3x + 2)(x-4) is the correct answer (option a)
