The error is that 9 shouldnt be written as nine it should be written as 3x3 or 3^2. So the answer should be 2^3 x 3^2 because 9 can be divided into even more prime factors of 72.
Since z is the midpoint, rz and zt must be equal
4x - 15 = 25
4x = 40
X = 10
Plug the answer in and rz equals 40-15 which is 25.
25 + 25 = 50
Or if you really wanted, since you know 25 is half, just add them together right off the bat. (25 and 25, I mean)
the answer is multiply the previous value by 2
Step-by-step explanation:
Answer: 1
Explanation: Doing -50+51 is essentially the same as 51-50
Use the metric relations,
AC*CD=BC^2
=>
5*CD=9^2
solve for CD
CD=9*9/5=16.2
