Answer:
<h2>8/15</h2>
Step-by-step explanation:

Any value of x makes this equation true or all real numbers
-2(3x+12) is the same this as -6x-24 when distributed
so it's -6x-24=-24-6x
her -6x just disappeared so she is wrong :)
D is the only one that makes any since
A=((8.9+8.9)/2) * 5.4 = 48.06P= 8.9*2 +6*2 = 28.4
