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)
15^2x is 225x. So, we have 225x-3=245. Adding three to both sides, we get 225x=248. Dividing by 225, we have x=248/225.
