Hello!</h2>
The answer is C. formulas
<h2>
Why?</h2>
Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.
A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.
Discarding the other given options:
A. decimals: Incorrect, decimals are a type of number which is not whole numbers.
B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.
D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.
E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.
Have a nice day!

Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)
20°24' + 24°30'
(20 + 24)°(24 + 30)'
44°54'
44 + 0.9
44.9
20°24' + 24°30'
(20 + 0.4) + (24 + 0.5)
20.4 + 24.5
44.9
The first and last table.
As the x increases by 2, the y goes down by 1, so both tables have the same rate of change which means they are the same function.
