256² = (256)·(256) = 65,536
Answer:
-5x=6
Step-by-step explanation:
What I did was subtract x by 5 since there is a 1 in front the x
Then subtract 11 by 5.
The fourth proportionals are bc/a and st/r
<h3>How to determine the fourth proportional?</h3>
<u>Segments a, b and c</u>
Let the fourth segment be x.
So, we have the following equivalent ratio
a : b = c : x
Express as fraction
a/b = c/x
Make x the subject
x = bc/a
<u>Segments r, s and t</u>
Let the fourth segment be x.
So, we have the following equivalent ratio
r : s = t : x
Express as fraction
r/s = t/x
Make x the subject
x = st/r
Hence, the fourth proportionals are bc/a and st/r
