Answer:
Step-by-step explanation:
Let length = x
Width = x + 5
Area = 36
Area = length × width
36 = x(x + 5)
36 = x^2 + 5x
x^2 + 5x - 36 = 0
x^2 + 9x - 4x -36 =0
(x^2 + 9x) - (4x + 36) = 0
x(x + 9) - 4(x + 9) = 0
(x -4)(x+9) = 0
x - 4 = 0 or x + 9 = 0
x = 4 or -9
But x can only be positive because it is a length
x = 4unit = length
Width = x + 5 = 4 +5 = 9unit
This equation is in point-slope form. To change it to standard form, you must distribute -1/2 to (x+4) to get -1/2x-2. Your equation should now be y-8 = -1/2x-2. You should then add 1/2x to both sides (to cancel out -1/2x on the right side). Now, you should have y+1/2x-8 = -2. Finally, add 8 to both sides (to cancel out -8 on the left side) and flip the x and the y to get a final answer of 1/2x+y = 6.
