24x-48 because you multiply the 8 with 3x and 8 with -6
25% percent
10/40 is also 1/4 simplified.
1/4 as a fraction is 25%, 25 times 4 equals 100.
<u>OR</u>
Use 1/4, but divide 1 by 4(fraction is also division)
You get 0.25
Turn this into a percent by moving the decimal point to the right 2 times.
The answer is 25%
Answer:
A, it's the only one with a number greater then 1
See explanation below.
Explanation:
The 'difference between roots and factors of an equation' is not a straightforward question. Let's define both to establish the link between the two..
Assume we have some function of a single variable
x
;
we'll call this
f
(
x
)
Then we can form an equation:
f
(
x
)
=
0
Then the "roots" of this equation are all the values of
x
that satisfy that equation. Remember that these values may be real and/or imaginary.
Now, up to this point we have not assumed anything about
f
x
)
. To consider factors, we now need to assume that
f
(
x
)
=
g
(
x
)
⋅
h
(
x
)
.
That is that
f
(
x
)
factorises into some functions
g
(
x
)
×
h
(
x
)
If we recall our equation:
f
(
x
)
=
0
Then we can now say that either
g
(
x
)
=
0
or
h
(
x
)
=
0
.. and thus show the link between the roots and factors of an equation.
[NB: A simple example of these general principles would be where
f
(
x
)
is a quadratic function that factorises into two linear factors.
