The given question is wrong.
Question:
Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).
Answer:
Option C:
3(xa) + 2(x + b)
Solution:
Given expression is 2(x + b) + 3(xa).
To find the equivalent expression using commutative property of addition.
Let us first define the commutative property of addition.
a + b = b + a
You can add in any order.
Now, write the given expression using commutative property.
2(x + b) + 3(xa) = 3(xa) + 2(x + b)
Option C is the correct answer.
Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.
Answer:
Good Luck!
Step-by-step explanation:
First, it is important to know that speed is equal to distance divided by time. I took a picture of my work. Let me know if you still have questions or cannot read something I've written. Thank you!
The most Kilometers traveled per one hour was traveled by THE BOAT at 75 Km/h. Therefore, the boat had the fastestaverage speed.
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.
Answer:
51.41 g
Step-by-step explanation:
70.61 - 19.2 = 51.41
u minus the amount he poured already from the total
to find how much more he had to pour
51.41 + 19.2 = 70.61
