(rs-s^2-rt +st)(t-r)
= ts^2-rt^2+st^2-sr^2-rs^2+tr^2
Answer:
see below
Step-by-step explanation:
m/n = 1/7
Using cross products
7m = n
This is a direct proportion
Answer:
units
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2
you have that a = 16 and c = 23, so:
16^2 + b^2 = 23^2
256 + b^2 = 529
b^2 = 273
b = 
The answer would be 10.976.
