You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14
Answer: 0.25 or 1/4
Step-by-step explanation:

Answer:
7.4 x 10^7
Step-by-step explanation:
3.98 x 10^8 - 3.24 x 10^8 = 0.74 x 10^8 (not scientific notation, because it isn't full number)
0.74 x 10^8 ---> 7.4 x 10^7
- got seven by counting the spaces it moved over (right decrease, while left increases)
