Answer:
b=√119
Step-by-step explanation:
a2+b2=c2
(5×5)+(b2) =(12×12)
25+b2=144
b2=144-25
b2= 119
b=√119
Let's call the width
and the length
based on this, we can make two equations based on the first and second sentences in the problem.


If we substitute
for
into the second equation, we can make the following:


- Use the Distributive Property


- Subtract 4 from both sides

- Divide both sides by 4 and simplify
Now, let's find
:

The length of the rectangle is
and the width of the rectangle is
.
Is there a diagram I can look at?
You take the total number of picture and multiply it by .12, which will get you the total number of black and white photos only.
600(.12)= 72
