-8,-3 if i read that correctly, that should be the answer.
Answer:
c) -20x^2+14x+12
all real numbers
Step-by-step explanation:
So (fg)(x)=f(x)g(x)=(-4x-2)(5x-6).
Need find the expression in standard form we need to use foil:
First: (-4x)(5x)=-20x^2
Outer: (-4x)(-6)=24x
Inner: (-2)(5x)=-10x
Last: (-2)(-6)=12
--------------------------Add like terms:
-20x^2+14x+12
Polynomials have domain all real numbers.
There are no restrictions on what x can be. For every number you plug in, you will get a number back.
Answer:
x=67
Step-by-step explanation:
Sum of all angles is 180
36+77+x=180
113+x=180
x=180-113
x=67
