Answer:
B
Step-by-step explanation:
A division between two roots that have the same index can be rewritten as a division between the two terms with a unic root

</h2>
When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:

So the components are:
- Measurements of the original object
- Measurements of the drawing
- Scale factor
In this item, it can be seen that from an expression of,
(4 + 5i) + (-3 + 7i)
Aiko transformed the equation by factoring out the i's from the expression and wrote it as,
(4 + 5)i + (-3 + 7)i
Now this is wrong because i there is not a variable but a notation that 5 and 7 are imaginary numbers. In fact, she cannot factor out the i's because it is not present in both -3 and 4. The answer therefore to this item is the last sentence, "Aiko incorrectly used the distributive property by combining ..."
Solving
we get 
Step-by-step explanation:
We need to solve: 
It can be solved using the exponent rule. If bases are same, then the exponents are added. i.e 
Applying exponent rule:

Another exponent rule says: 
So,

So, solving
we get

Answer:
4.189 radians
Step-by-step explanation:
Given data
θ=240 degrees
Let us convert from degrees to radians
Angle in Radian= Angle in degree* π/180
Substitute
Angle in Radian= 240* π/180
Angle in Radian= 4* π/3
Angle in Radian= 4* 3.142/3
Angle in Radian=12.568/3
Angle in Radian=4.189 radians
