Answer:
2x² +2x - 12
Step-by-step explanation:
area of rectangle = length X width
length = x+3
width = 2x - 4
Area = (x+3)(2x-4)
= x(2x-4) +3(2x-4)
= 2x² - 4x + 6x - 12
= 2x² +2x - 12
(jk)(x)= j (k(x)) = j(9-2x)
= -7(9-2x) = -63 + 14x
but i see there is no such option. may be second option is typo.
so you can select 2nd option
X = y - 5
x = 1 - y / 3
I hope this helps. :)
