Answer:
An equivalent algebraic expression of -(b-5) using distributive property is
-b+5
Step-by-step explanation:
We need to use distributive property to solve the expression -(b-5)
The distributive property states that 
Using distributive property to solve the expression -(b-5)
So, an equivalent algebraic expression of -(b-5) using distributive property is
-b+5
False, they would be called Complementary
P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50
284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99
So firstly, factor out h on the left side: 
Next, divide both sides by h: 
Lastly, subtract both sides by b and your answer will be
