Answer: The student is wrong. The correct algebraic expression is 9(n + 13)
The algebraic expression is represented as follows:
The sum of a number and 13 is represented as follows:
Let
n = the number
Therefore,
The sum of a number and 13 is:
n + 13
9 times the sum of a number and 13” can be translated as follows:
9(n + 13)
Therefore, the student is wrong.

Yes
Step-by-step explanation:
From calculations, we can say that the given tiles will not fit together perfectly.
<h3>How to find the sum of interior angles of a Polygon?</h3>
If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.
Expression for the measure of the interior angle of a polygon,
Interior angle of a polygon = [(n - 2) * 180]/n
Interior angle of a pentagon = [(5 - 2) * 180]/5 = 108°
Interior angle of a hexagon = [(6 - 2) * 180]/6 = 120°
Interior angle of an octagon = [(8 - 2) * 180]/8 = 135°
To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°
Sum of all interior angles = 108° + 120° + 135° = 363°
Therefore, given tiles will not fit together perfectly.

When the son is 8, the father is five times that so 8*5 = 40, difference between their ages is 32
twice as old 32*2 = 64
The father will be 64.
