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!
Answer:
The answer should be choice D.

A = bh
60 in.² = b(4)
60/4 = b
b = 15 inches

The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.
To find the x-intercept, set y = 0:
-5x + 1/5(0) = 15
-5x + 0 = 15
-5x = 15
Divide both sides by -5:
x = -3.
Therefore, the x-intercept is (-3, 0).

Answer:
La razón de niñas a niños en la guardería es de 2 niñas por cada 3 niños.
Step-by-step explanation:
Una razón es una división entre dos números, generalmente en forma racional (fraccionaria). La razón de niñas a niños en la guardería es la cantidad de niñas dividida por la cantidad de niños de la dicha guardería, Es decir:
