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.
3.78 Per hour should be the answer
<span>To find the odometer reading before the trip, we just need to subtract the distance that Lee drove in recent vacation form the current odometer reading in his car.
We know for our problem that Lee drove </span>2,904.6 kilometers and the current odometer reading on his car is <span>99,532.4 kilometers, so lets perform our operation:
</span>Odometer reading before the trip=
We can conclude that <span>the odometer reading before the trip was
96,627.4 kilometers.</span>

Below
Step-by-step explanation:
The surface are is given by this formula:
Sa= area of the base*the heigth + the area of the base *2
●●●●●●●●●●●●●●●●●●●●●●●●
2)
The base here has a triangular form.
Let A be the area of this triangle.
A= (6*8)/2 = 24 cm^2
Sa = A* 6 + A*2
Sa= 24*6 + 24*2
Sa = 192 cm^2
●●●●●●●●●●●●●●●●●●●●●●●●
The base here is a circle.
The area of a circle is :
A= r^2 * Pi
r is the radius (here 12 km)
A = 12^2* Pi
A= 144 Pi cm^2
Sa = 2*A + A* h
Sa = 7* 144* Pi + 2* 144* Pi
Sa= 4071.504
So the surface area is aporoximatively 4072 km^2
