Answer:
D
Step-by-step explanation:
Lets go case by case.
Given the roots, a factor will be part of the equation if for some of the roots the factor becomes null, i.e., equal to 0.
Is there any root that makes (x+3)=0? No, as it only becomes 0 for x = - 3 and -3 is not a root. So A NO!
Is there a root that makes (x-1)=0? No, as it only becomes 0 for x=1 and 1 is not a root. So B NO!
(x-4)=0 only for x=4, and as 4 is not a root, C NO!
The last, (x-3)=0 if x=3. As 3 is one of the roots, (x-3) is a factor of our equation!
D is the only correct option!
A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function. What is the catch? There can be at most one output for every input.
I would be happy to help, is there anything else like the options or the graphs you could add?
Answer:
84mm²
Step-by-step explanation:
A=Formula for area of a triangle: 
(B×H)
A= (14×12)
A= (168)
A= 84mm²
Answer:
<h2>x = 14</h2><h2 />
Step-by-step explanation:
7x + 9 + 5x + 3 = 180
7x + 5x = 180 - 3 - 9
12x = 168
x = 168 / 12
x = 14
