Accordinly to the details, i think that A could work.
Answer:
x=-1
Step-by-step explanation:
The lines stand for absolute value ( how far a number is from 0), so each number should be a positive, then you just solve for x. Isolate x, then divide on both sides, and you should get -x=1, which is equal to x=-1.
You've written "then" before 3, so i assume the real question is:
(40 * 40 * 40 + 26 - 98 + 45 * 78 * 78 * 78) / 3
Use "PEMDAS" first solve under the parenthesis, then after it.
= (64000 + 26 - 98 + 21354840) / 3
= 21418768 / 3
= 7139589.33
In short, Your Answer would be: 7139589.33
Hope this helps!
