It will be 12 because there is 12 inches in a foot
Answer:
The length of the longest side are all real numbers greater than 39 inches and less than 51 inches
Step-by-step explanation:
we know that
In an obtuse triangle

where
c is the length of the longest side
a and b are the two shorter sides
Convert the dimensions in inches


substitute the values



Applying the triangle inequality Theorem
1) 

2) 

therefore
The length of the longest side belong to the interval 
All real numbers greater than 39 inches and less than 51 inches
Answer:wait can you umm rewrite this i dont get it
Step-by-step explanation:
Answer:
You are 25
Step-by-step explanation:
This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.
We proceed in a stepwise manner
let say what I have is x
1. Subtract 5 from me
(x-5)
2. Then add 2
(x-5)+2
3. If you subtract 10
(x-5)+2-10
4. And then add 3
(x-5)+2-10+3
5. you get 15
(x-5)+2-10+3=15
what am I is the question we need to answer, we do this by solving for x
x-5+2-10+3=15
x-15+5=15
x-10=15
x=15+10
x=25
