For this question, you must use the Pythagorean theorem.
a^2 + b^2 = c^2
In this situation c=16 and a=6
First do 16^2. This equals 256
Second do 6^2. This equals 36
Now, subtract 36 from 256 and fond the square root.
Your answer should be 14.8
Step-by-step explanation:
mean add upp all the numbers and divide by how many they are
Simple....
you have:
3x-9=7x+12
To even solve this....isolate the variable your are trying to solve for....
3x-9=7x+12
-3x -3x
-9=4x+12
-9=4x+12
-12 -12
-21=4x
Simplify.....


Thus, your answer.
