Question
For What value of X is 
undefined ?
- -8
- -3
- 0
- 4
- 9
Hint:
The expansion of 
.
We are asked to find the value for which the expression is undefined.
The correct answer is: -3
Step 1 of 2:
Simplify the expression and cancel out the common factors,
Thus, the simplified expression is 
.
Step 2 of 2:
The expression is undefined when the denominator is equal to zero. So, we have:
(x - 3)(x + 3) = 0
x = -3 & x = 3
Therefore, correct option is: b.
Division of an expression by zero is not defined.

A Basketball coach is considering three players for most valuable player . The table shows the proportion of shots each player made of the shots they attempted.
a) For a technical foul , the team can pick any player they want to shoot the free throw. Which player should the team pick ?
b) Which player is most successful with their field goal shots? Explain.
c) Rank the players by the percentage of the 3- point shots each made .
d) If all the players attempted the same number of shots , which player would you choose as the most valuable player? Justify your answer.
In this question, it can be explained further:
A. Kimberly: 0.857 > 4/5 > 71%
Here, Kimberly's free throws have the highest proportion.
B. Martin: 49.5% > 9/20 > 0.448
Here, Martin's proportion of field goals is the highest.
C. Corey: 0.338 > 1/3 > 32%
Kimberly > Corey > Martin
From the above explanation, we can conclude Kimberly is first, Corey is second, and Martin is third.
I'd go with Kimberly because he has a higher percentage on all shots than the other two players.

Adam wraps the top edge of the gift box shown with gold ribbon. The top and bottom edges of the box are square. If Adam has 24 . 25 cm. of gold ribbon , does he have enough to decorate the top of the box ?
The volume formula is a mathematical expression that can be used to calculate the total amount of space (vacuum) occupied by any three-dimensional object.
The volume of an object is the amount of three-dimensional space occupied by the object or shape. It is typically measured in cubic units. In other words, the volume of any object or container is its ability to hold the amount of fluid (gas or liquid). Using arithmetic formulas, the volume of three-dimensional mathematical shapes such as the cube, cuboid, cylinder, prism, and cone, among others, can be easily calculated.
Cuboid Formula
V = l × w × h
l represent Length
w represent Width
h represent Height
