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

What is Y-3x=-2 and Y+x=-6

love history [14]

Rearranging the first equation gives:

$y=3x-2$

Substituting this into the other equation gives:

$y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1$

If x=-1:

$y+(-1)=-6
\\y=-5$

So x=-1, y=-5
