Answer:
x = 4
Step-by-step explanation:
The measures of all angles in this geometry are 90 degrees.
21x +6 = 90
21x = 84 . . . . . subtract 6
x = 4 . . . . . . . divide by 21
Answer:
Ground Morgans are 52% the price of Floating Jumps.
Step-by-step explanation:
A pair of Ground Morgans 
is 20% less expensive than a pair of Elite Butterflies 
, this means
<em>(GM is 80% the price of EB's)</em>
Elite Butterflies are 30% more expensive than Cloud Trainers 
's, this means
<em>(EM's is 130% the price of CT's)</em>
Cloud Trainers are 50% less expensive than Floating Jumps 
, this means
<em>(CT is 50% the price of FJ)</em>
Now, if we want the price of Ground Morgans in terms of Floating Jumps, then, since EB = 1.3 CT,
and since CT = 0.5F, we have
.
Simplifying we get
Ground Morgans are 52% the price of Floating Jumps.
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.
