Answer:
Step-by-step explanation:
2x² -x - 6 = 2x² - 4x + 3x - 3*2
= 2x*(x - 2) + 3*(x - 2)
= (x-2)(2x + 3)
A = 2x² -x - 6
A = (x - 2)(2x + 3)
length*width = (x - 2)(2x + 3)
length * (2x +3) = (x - 2)(2x + 3)
length = x - 2
i think its 1cm/10mm = 12.5/x
and the answer like the thing is 125 mm = 12.5
im from korea so i know mm/cm
3 x 2 = 6. 6 - 2 = 4.
4 = 3(2) - 2.
t = 2
Collecting like terms,
Since the signs change when its position changes.
