Answer: at most 15 pairs of socks
Step-by-step explanation:
Let the number of pair of socks of her sister be , and let the number of pairs Lucy has be
.

subtract 12 from both sides
Therefore , the sister has at most 15 pairs of socks
The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .
let's solve for area of rectangle :
Now, Area of Triangle :
So, the area of the shaded region in terms of x :
And since, Area of Shaded region = 44 cm²
By equating the area, we get
Value of x = 2
