Answer:
y =3x + 12
Step-by-step explanation:
Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99
1) True
2)True
3) False
4) True
Hope this helps!! :)

Answer:
144
Step-by-step explanation:
In a 45-45-90 triangle, the ratio of the lengths of the sides is:
leg : leg : hypotenuse
1 : 1 : sqrt(2)
Draw a segment from the center point to the bottom side of the square that is perpendicular to the bottom side. Now you have a right triangle. The hypotenuse is 6sqrt(2). The legs are 6. The bottom leg is half the side of the square.
side of square = 2 * 6 = 12
area = side^2 = 12^2 = 144
