Answer:
a=-2
b=4
c=-3
Step-by-step explanation:
You just compare -2x^2+4x-3=0 to
ax^2+bx+c=0
There is really no work here.
I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total

Given: The area of a square field is 841 sq.m
Since side of square = √Area
So, side of square field =
Thus , side of square field = 29 m
Perimeter of square = 4( side) = 4(29) = 116 m
Let x be the breadth of rectangle then 2x be the length
Perimeter of rectangle = 2 (length+breadth) = 2(2x+x)= 2(3x)=6x
As per question, perimeter of rectangle= Perimeter of square

Length : 
Area of rectangle = length x breadth

Area of rectangle = 
Answer:
The answer to your question is There is no solution, the lines are parallel.
Step-by-step explanation:
Data
Equation 1 x + y = 2
Equation 2 x + y = -1
Solve for y
Equation 1 y = -x +2
y = - x + 2
Equation 2 y = - x - 1
See the graph below
These lines do not cross, so there is no solution. They are parallel.
If the lines have crossed, there would be a solution.
