Answer:
{(-3,-4), (-4,-3), (3, 4), (4,3)}
Step-by-step explanation:
because x should not be the same in more than one pair
10
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10
Note: opposite operation of square is square root
