Answer:
None of the options are correct, as the answer is <u>2x - 18 = 68.</u>
Step-by-step explanation:
The <u>2x</u> represents the length (x) being half of the width (68)
The <u>-18</u> represents the width (68) being 18 less than twice the length (2x)
The answer is 9.65x10^14 because in order for the decimal point to be between 9 and 6 you need to move 14 decimal places back
