Answer:
n + 11 and 11 + n
Step-by-step explanation:
Let n be the unknown number,
n is increased by 11,
That is, n + 11
By the commutative property of addition,
The expression would be,
11 + n
For drawing a model that shows n + 11
Take two boxes in which first shows n and second shows 11 and add them,
Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.
Hey there Caleb!
To start of, the sentence was clear on that it said . . .

The statement listed above is the (key) point. We need to keep this in mind.
So, now that we know this.
We would use the mathematic (Ф)
So,sense we know that a (hexagon) had it's (6) shapes, we would do
. . .
Ф = 360° : 6 = 60°
Your correct answer to this question would be
. . .

Hope this helps.

Where the rest of the question?
Answer:

Step-by-step explanation:
From law of indices
Alright, lets get started.
One report takes to file an average of = 45 minutes
Means 12 reports takes to file time = 12 * 45 = 540 minutes
12 reports filing total time = 540 minutes
We are asked to find time to file 75 % of them.
Which means 75 % of 540
= 540 * 75/100
= 540 * 0.75
= 405 minutes
We could convert it into hrs dividing with 60.
405 / 60 = 6.75 hrs
Means it will take 6.75 hrs to file 75% of them: Answer
Hope it will help :)
