The expression 2 * √36 + 9 evaluates to 21.
The expression 2 * √36 + 9 evaluates to 21 when you follow the order of operations known as BODMAS. You first calculate the square root of 36, then multiply the result by 2 and finally add 9.
To evaluate the given mathematical expression, we must first understand the order of operations, also known as BODMAS.
The acronym BODMAS stands for Brackets, Orders, Division/Multiplication (from left to right), Addition/Subtraction (from left to right). It represents the sequence in performing mathematical operations.
Let's apply this to the question: 2 * √36 + 9?
First, consider the 'Order', which is the square root (√). The square root of 36 is 6.
Next, apply the 'Multiplication'. So, 2 multiplied by 6 equals 12.
Finally, apply the 'Addition'. 12 plus 9 equals 21.
So, the expression 2 * √36 + 9 evaluates to 21.

Step-by-step explanation:
p of one game? write and solve an equation.
The equation for the cost value is 154.99 + 4p = 224.97 and the price for one game is $17.50.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Let's call the price of one game "p".
Serena bought four games, so the total cost of the games is 4p.
We know that the total amount she spent, including the game system, is $224.97.
So we can write an equation -
154.99 + 4p = 224.97
To solve for p, we can isolate the variable on one side of the equation by subtracting 154.99 from both sides, and then divide by 4 -
4p = 69.98
p = 69.98 / 4
p = 17.495
Rounding to two decimal places, the price of one game is $17.50.
Therefore, the price value is obtained as $17.50.

The simplified form of expression is 9 (3 - 2r).
Used the concept of distributive property,
The distributive property states that an expression that is given in the form of A (B + C) can be solved as A × (B + C) = AB + AC.
Given that the expression is,
27 - 18r
Apply the distributive property on the expression and it can be written as,
27 - 18r
Since LCM {27, 18} = 9
So, take 9 as a common term,
27 - 18r = 9×3 - 9×2r
= 9 (3 - 2r)
Therefore, the solution of the expression is, 9 (3 - 2r)
