You have to cut it up as you did there and look at it as three different rectangles, one having a length of 2 and a width of 1, another having a width of 2 and a length of 3 and lastly on having a width of 3 and a length of 4. When you find the area of each just add them all together
The answer is -9 because when there are this lines around the x it mean that you need to make it opposite. Therefore x=-9

Answer:
D. 18 ml of the mixture is vinegar
The equation that we have been given is:
= 
In order to solve for the value of 'x', we'll have to use cross-multiplication.
Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.
Let's cross-mutliply the numerators and denominators:
= 
9*(x+2) = 4*(3x)
Distribute the numbers into the parentheses.
9x + 18 = 12x
Simplify by subtracting both sides by 9x:
9x - 9x + 18 = 12x - 9x
0 + 18 = 3x
18 = 3x
3x = 18
Divide both sides by 3:
= 
<u>x = 6</u>

Let me know if you'd like me to explain anything I did here.
