Find the midpoint of np given n(2a, 2b) and p(2a, 0)

Which equation and solution can be used to solve this problem? thirteen less than a number is sixteen. 13-n=16: add 13 to both sides. the answer is 29. n+13=16: subtract 13 from both sides. the answer is 3. n+16=13 subtract 13 from both sides. the answer is 3. n-13=16: add 13 to both sides. the answer is 29.

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

What is the approximate value of the correlation coefficient for the given graph? a. 1 b. 5 c. 3 d. -1
