Answer:
see explanation
Step-by-step explanation:
Given
, 
Factor the denominators of both fractions
, 
The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)
Multiply numerator/denominator of first fraction by (a + 7)
Multiply numerator/denominator of second fraction by (a + 5 )
, 
, then
, 
The way you put it is confusing. I'll answer but the way you put it was confusing to me.
4cm•2=8cm which is the length of the red paper so therefore Red paper= 4cmx8cm.
Then your going to take 3cm-4cm= 1cm
Next your going to solve for 7cm-8cm=1cm
Which leaves you with an answer of 1cmx1cm more of visible red paper.
You have to simplify like this
(-5)(-8)=40
Answer:
392.00
