A. F(x)= 3x+6 =12
3x = 12-6
3x = 6
x=2

B. x=10, f(x)= 3*10+6 = 30+6 = 36

C. f(x) = 3x+6 = 6
3x = 6-6
3x=0
x=0

D. x=5, f(x) = 3x+6 = 3*5+6 = 15+6 = 21

Write as a product: ax^2+ay^2–bx^2–by^2+b–a

Vesna [10]

Answer:

$\large\boxed{ax^2+ay^2-bx^2-by^2+b-a=(a-b)(x^2+y^2-1)}$

Step-by-step explanation:

$ax^2+ay^2-bx^2-by^2+b-a\\\\=(ax^2-bx^2)+(ay^2-by^2)+(b-a)\qquad\text{use the distributive property}\\\\=x^2(a-b)+y^2(a-b)-1(a-b)\\\\=(a-b)(x^2+y^2-1)$
