Answer:
should be 3^X = 7 and X = log7/log3
Step-by-step explanation:
The perimeter of a triangle is found by adding all the three sides.
Let's call the third side "x"
So,
6+9+x = 23
15+x = 23
x = 8
Answer:
ab
Step-by-step explanation:
When all of the variables are the same in a problem, think of them as the same term. They can be added and subtracted just as you would add and subtract normal numbers.
For example if I have 5 bananas on a table and take away 3 bananas. I only have two bananas left (2b). It's the same when there are variables!
Subtract 9 from 3:
-6ab+7ab
Add -6 to 7:
ab
Your final answer is ab!
Depending on the answer of the problem if it’s negat the sign is so on and so fourth
