Which of the following expressions can be written as 12(a + b)?
a.(12 + a) ∙ (12 + b)
b.12a + 12b
c.(12 + a) + (12 + b)
d.12a ∙ 12b
Answers
Answer:C(12+a)+(12+b)
Step-by-step explanation:
Answer: 12a + 12b
Step-by-step explanation: Use the distributive property. The property is that you can take the 12 and multiply it by both letters inside separately.
12(a+b) = (12 * a)+(12 * b) = 12a+12b
It's easier to see a picture of how the distributive property works.

a) Is this a proportional relationship?
b) If this is a proportional relationship, what is the constant? Write N/A if it is not proportional.
c) If this is a proportional relationship, write a direct proportion equation. Write N/A if it isnot proportional.
Answers
a) Yes, This is a proportional relationship.
b) The value of constant is, 1/3.
c) The direct proportion equation is,
⇒ y = 1/3x
Where, y represent the cost and x represent the number of days.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
We have to given that;
The relation is,
X-number of days Y- cost
6 2
9 3
24 8
3 1
Let number of days = x
And, Cost = y
So, By definition of proportional, we have;
⇒ y = kx
Where, k is constant of proportionality.
Now, By the given relation, we get;
⇒ 2 = k × 6
⇒ k = 2/6
⇒ k = 1/3
And, y = kx
⇒ 3 = k × 9
⇒ k = 3/9
⇒ k = 1/3
Hence, The given relation is in proportion.
And, The value of constant of proportionality = 1/3
Thus, The direct proportion equation is,
⇒ y = 1/3x
Where, y represent the cost and x represent the number of days.

Through graphical analysis, the process can be quickly understood, which improves communication and gives further analysis a clear direction. Bank A has the better exchange rate, with $1,700 equaling 8670 kroner.
What is a graphical analysis?A graphical analysis is a graphical representation of data that uses graphs, figures, and charts. It is particularly useful for managers who must process large amounts of data. A large amount of data is presented in an understandable format in this type of analysis.Through graphical analysis, the process can be quickly understood, which improves communication and gives further analysis a clear direction. It is an important tool for determining the causes of data variation, which aids in understanding the process and potential root causes.Therefore,
Bank A have the more exchange rate.
exchange rate :
Bank A gives 5.1 kroner per Dollar.
Bank B gives 5.0 kroner per Dollar.
Mia get :
1700 × 5.1 = 8670 kroner.
Hence, Bank A has the better exchange rate, with $1,700 equaling 8670 kroner.
