Answer: - 2x^2 + 4x + 3
Step-by-step explanation:
( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)
Take out parentheses:
- x^2 - 4x - 5 - x^2 + 8x + 8
Write in a way so that like terms are grouped together:
- x^2 - x^2 - 4x + 8x - 5 + 8
Combine 'x^2' terms:
- 2x^2 - 4x + 8x - 5 + 8
Combine 'x' terms:
- 2x^2 + 4x - 5 + 8
Combine integers:

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
-------> equation A
-----> equation B
Isolate the variable y in the equation B
------>
Equation A and equation B are equal
Line A and Line B are the same
therefore
The system of equations is a consistent dependent system
The system of equations has infinitely solutions
All ordered pairs belong to the line are solutions of the system
see the graph in the attached figure
y2 = -5x - 2
y1 = y2, => infinitely many solutions

The width of the rectangle is 2.5 cm. Therefore, option D is the correct answer.
Given that, a rectangle has an area of 25 square centimeters and a length of 10 centimeters.
What is the area of a rectangle?
The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Now, put length = 10 cm and area of a rectangle = 25 cm² in area of rectangle formula
That is, 25 = 10 × width
Width = 2.5 cm
The width of the rectangle is 2.5 cm. Therefore, option D is the correct answer.
