Answer:
I think that it is B because its the only answer that makes sense
Step-by-step explanation:
(x -1)(x +4) = 0
x² +3x -4 = 0 . . . . . . probably the form you're looking for
The perimeter of each is the sum of the lengths of its sides.
Triangle Perimeter = 16 + 4x-3 +3x = 7x+13
Square Perimeter = 2x +2x +2x +2x = 8x
If these are equal, you have
![7x+13=8x\\\\13=x\qquad \mbox{subtract 7x}\\\\26=2x\qquad \mbox{multiply by 2}](https://tex.z-dn.net/?f=7x%2B13%3D8x%5C%5C%5C%5C13%3Dx%5Cqquad%20%5Cmbox%7Bsubtract%207x%7D%5C%5C%5C%5C26%3D2x%5Cqquad%20%5Cmbox%7Bmultiply%20by%202%7D)
The length of a side of the square is 26 units.
