Answer:
4/5
Step-by-step explanation:
This is because it is a fraction
well, let's first off, expand the expression, 3x(x-4) => 3x²-12x, which we can also write as
f(x) = 3x² - 12x + 0
now, this is a quadratic equation with a leading term with a positive coefficient, namely its graph is a parabola, or a Cup-Shaped figure, so the graph comes from the top, goes down down down, reaches a U-turn, then goes back up up up.
the U-turn, or vertex of the quadratic, is the lowest point in the "cup".

Answer:

Step-by-step explanation:
we know that
<em>Joey can paint a room in 2 hours</em>
That means
Joey can paint the 100% of the room-------> 2 hours
so
In 1 hour ------> can paint 100%/2=50%
<em>Chelsea can paint a room in 3 hours</em>
That means
C<em>helsea</em> can paint the 100% of the room-------> 3 hours
so
In 1 hour ------> can paint (100%/3)=33.33%
therefore
Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%
by proportion

Divide 112 by the possible answers. If the answer comes out even it is a factor. If it comes out with a decimal it is not a factor:
112 / 2 = 56, so 2 is a factor.
112/3 = 37.333., 3 is not a factor.
112 /4 = 28, 4 is a factor.
112 / 6 = 18.66, 6 is not a factor.
112 / 7 = 16, 7 is a factor.
112/8 = 14, 8 is a factor.
The factors are: 2 , 4 ,7 and 8.
