Answer:
D. difference of squares
Step-by-step explanation:
Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.
a^2 -b^2 = (a -b)(a +b)
x^2 -9 = (x -3)(x +3)
Answer:
C. y= 6.18x + 10.9
Step-by-step explanation:

Answer:
angle ABC is 48⁰
Step-by-step explanation:
angle BCD will be 111⁰ it will be equal to DAB.
111+111+90=312⁰
kite is a quadrilateral so its angles add up to 360⁰
360-312=48⁰
