Answer:
Area of Rectangle = length times width
lets say length = 2x-4
width = x+5
Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.
With that being said:
length * width = area
(2x-4)(x+5)=area
Y - 4 + 8
y +4
x2 + 4x + 4
x + 2 + 2
x + 4
x2 + 2x+ 1
x + 2 + 1
x + 2
j2 + 40j + 400
j + 20 + 200
j + 220
25n2 + 40np + 16p2
25n + 20p + 16p2
25n + 10 + 4
25n + 14
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
