Answer:
(x + 7) (x - 3)
Step-by-step explanation:
Find 2 numbers that add to 4 and multiply to -21
(x + 7) (x - 3)
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees

II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
