Answer:
D. 
Step-by-step explanation:
we are given
Firstly, it is reflected over x-axis
we know that for reflection about x-axis , we can replace y as -y
we get
now, it is vertical shift up by 4 units
so, we can add 4 to y-value
we get
1.)11x^2-3x
2.)8x+1-x^2
3.)-x^2-x+8
4.)-2y+10-x^2
Area of a square quilt = 289 square inches
Area of a smaller square quilt = 121 square inches
Area of a square = a²
Side length of big square quilt = √289 in² = 17 inches
side length of small square quilt = √121 in² = 11 inches
Perimeter of big square = 17 inches * 4 = 68 inches
perimeter of small square = 11 inches * 4 = 44 inches
difference = 68 inches - 44 inches = 24 inches.
