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
Answer:
<h2><u>440 ft.²</u></h2>
Step-by-step explanation:
Surface area of the object = 2 (lw + wh + hl) = 2 (10× 6 + 6 × 10 + 10 × 10)
= 2 ( 60 + 60 + 100) = 2 × 220 = 440 ft.²
If this is supposed to be

Then this can simply be reduced to

by the double angle formula for cosine
