Answer:
$79.20
Step-by-step explanation:
fixed charged of $19 x 4 months = $76.00
additional charged of $0.04 x 20 = $0.80 x 4 months = $3.20
Therefore, $76.00 + $3.20 = $79.20
 
        
             
        
        
        
•  Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b²    <———    expanded form  (this is the answer).
I hope this helps. =)

Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board =  feet
 feet
Also, she need to cut the board into 11 pieces.
