Answer:

9) 9 times a number

10) 14 is the difference between a number and 8

11) 24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12) A number increased by 12

Step-by-step explanation:

There are several ways of writing these into a verbal phrase, but this is how I would do it:

9) 9 times a number

10) 14 is the difference between a number and 8

11) 24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12) A number increased by 12

Give two examples that show how using parentheses can change the order I. Witch operations are performed in an expression

pantera1 [17]

The order of arithmetic operations is given by the acronym PEMDAS, which means
Parentheses,
Exponents,
Multiplication,
Division,
Addition,
Subtraction.

These two examples illustrate how the use of parentheses can change the order.

Example 1:
5+7/3x4-2/5 has an answer of 13.933.

Use PEMDAS to obtain
5+(7/3)x4-(2/5)
= 5+(2.3333x4)-0.4
= 5+9.3333-0.4
= 14.3333-0.4
= 13.933

If we apply the parentheses: (5+7)/3x4-2/5
The result is
(12/3)x4-(2/5)
= (4x4)-0.4
= 16-0.4
= 15.06
which is a different answer.

Example 2:
8/3²x5+4 has the answer 8.444

Use PEMDAS to obtain
8/(3²)x5+4
= (8/9)x5+4
= (0.8889x5)+4
= 4.4444+4
= 8.4444

If we apply the parentheses (8/3)²x5+4:
The result is
2.6667²x5+4
= 7.1113x5+4
= 35.5565+4
= 39.5565
which is a different answer.

If the cube has a side length of 12 inches, what is the surface area of the cube?

Ne4ueva [31]

The equation for surface area on a cube is 6 * L^2, where L is side length. Essentially, six squares of equal size
12^2=144
6 * 144=864
I hope you found this both helpful and explanatory

In the given graph, line AB is reflected over the:

melamori03 [73]

Hey there!

The word reflected means when something is basically coping everything that you do. So, for example, when I look in a mirror, the mirror would reflect everything that I would do.

So, from looking at the graph above, as we should <em>remember </em>the $\left[\begin{array}{ccc}\boxed{x-axis}\end{array}\right]$ is the $axis$ that is (horizontal) and the $y-axis$ is the $axis$ that is (vertical).

So, from knowing this information of graphs, we now know that $\left[\begin{array}{ccc}AB\end{array}\right]$ are reflecting over the $(x-axis)$ which is the line that is (horizontal).

Your correct answer would be . . .

$\boxed{\boxed{x-axis \ would \ be \ your \ answer}}$

Hope this helps you!
