Answer:


Step-by-step explanation:

To compute x times y must use foil on the right hand side.
First: 
Outer: 
Inner: 
Last: 
------------------------------------Add like terms:

----------------


Multiply top and bottom by bottom's conjugate:

Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:

Replace
with -1:



F(X) = 4x - 5
G(X) = 6x - 3
F(x) - G(x)
(4x - 5) - (6x - 3)
4x - 5 - 6x + 3
-2x - 2
-2(X + 1).
I believe this would be the simplified solution.
The correct answer would be D. because if the equation has a y-intercept (+4) than the line doesn't go through the origin.
Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
