Points L, M, and N are collinear with M between L and N. LM = 2x + 8 and MN is one half the length of LM. If LN = 42, write and solve an equation to find x.
<span>The answer is 454. Since the value of the ones digit is 4, the last digit is a 4. Next, since the ones digit is the same as the hundreds digit, the first digit would be 4. Finally, the middle digit is the tens place and would be 5 since the tens digit is 50.</span>
