Answer:
The answer that is <em>not </em>true when x = -4 is <u>B</u>.
Step-by-step explanation:
Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.
A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.
Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.
Finally D. -4/4 divided equals -1, so that would make it -1 = -1.
B is the only one that doesn't make sense, therefore you have your answer.

Answer:
 = 3 3/4 m^2
or 15/4 m^2
Step-by-step explanation:
The base is the triangle.  
A =1/2 bh
A = 1/2  (3 1/3 * 9/4)
Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3
A = 1/2 * 10/3 *9/4 
Re arranging
    =  1/2* 9/3 * 10/4
  = 1/2 (3) 5/2
  =15/4
Now writing as a mixed number
 = 3 3/4 m^2

So we are using the denominator 20. 
1/2 of 20 would be 10. 
So, out of 20 we multiply it by 10 since it is our numerator. 
Now, we have converted it to 100/200.
