<h3>How to simplify the expression?</h3>
The expression is given as:
Express x^2 - y^2 as (x + y)(x - y) and factorize other expressions
Rewrite the expression as products
Cancel out the common factors
Express 4x^2 - y^2 as (2x - y)(2x + y)
Cancel out the common factors
Take the LCM
Hence, the simplified expression is and the restriction is

Answer:
B (1 , 3) , D (1 , -2)
Step-by-step explanation:
∵ A (-3 , 3) , C (-3 , -2)
∵ They have the same x-coordinate
∴ AC is a vertical segment its length = 3 - -2 = 5
∵ The area of the rectangle = 20
∴ The width of it = 20 ÷ 5 = 4
∴ x-coordinate of B: -3 + 4 = 1
∴ y-coordinate of B : 3 ⇒ AB horizontal segment
∴ B (1 , 3)
∵ x-coordinate of BD is 1 ⇒ BD is vertical segment
∵ y-coordinate = 3 - 5 = -2
∴ D (1 , -2)

y=4x+8
Step-by-step explanation:
Answer: $10.40
Explanation:
First, find the cost of 1 box of pasta. 13/5 = 2.6, so $2.60 a box.
Next, find how many boxes there are. 48/12 = 4, so 4 boxes of pasta.
Finally, multiply 4*2.6 to get the final cost.
