Factor completely x^2 − 36.
(x + 6)(x − 6)
(x + 6)(x + 6)
(x − 6)(x − 6)
Prime
ANSWER
[tex] (x + 6)(x - 6)[/tex]
EXPLANATION
The given expression is
[tex] {x}^{2} - 36[/tex]
We write to obtain;
[tex] {x}^{2} - {6}^{2} [/tex]
Recall that;
[tex] {a}^{2} - {b}^{2} = (a - b)(a + b)[/tex]
We apply this difference of squares formula to get;
[tex]{x}^{2} - {6}^{2} = (x - 6)(x + 6)[/tex]
The correct choice is A
Answer:
(x+6)(x-6)

Which pair of expressions is equivalent for any variable value greater than zero?
Answer:
D. b+b+3c and 2b+3c
Step-by-step explanation:
The question wants us to find out expressions is equivalent for any variable value greater than zero. So let's analyse all the possible answers to find the correct one.
A. (x+3) and 3x+ 2
If x = 1 , we have:
(x+3) = 4 3x+2 = 5Both of the two sides are not equivalent
B. 4d+2e and 8d+e
If e=1 and d=1, we have:
4d+2e = 88d+e = 9Both of the two sides are not equivalent
C. f+f+f+g and 3fg
If f=1 and g=1, we have:
f+f+f+g = 43fg = 3Both of the two sides are not equivalent
D. b+b+3c and 2b+3c
If b=1 and c=1, we have:
b+b+3c = 52b+3c = 5Both of the two sides are equivalent
Or we will simplify the left side: b+b+3c = 2b+3c, hence 2b+3c = 2b+3c are apparent
So we choose D.

A restaurant purchased 160 boxes of mustard packets. Each box contained 103 packets of mustard. How many mustard packets in total did the restaurant purchase?
Answer:
Total number of mustard packets = 16,480
Explanation:
A restaurant buy mustard box = 160
Each mustard box contain packet = 103 packet
In order to find the total number of packets
Total number of packet = (number of mustard boxes)*(number of packets in a box)
Now put the values in given formula
Total number of packet = 160 * 103
Total number of packet = 16,480
final answer, I hope it helps

Solve P=hr(1-d) for d
To solve the given equation [tex] P=hr(1-d) [/tex]
By using the distributive property "a(b+c)=ab+ac"
[tex] P=hr-hrd [/tex]
[tex] hrd=hr-P [/tex]
[tex] d=\frac{hr-P}{hr} [/tex]
[tex] d=1-\frac{P}{hr} [/tex]
Therefore, [tex] d=1-\frac{P}{hr} [/tex] is the value of 'd'.

Step-by-step explanation:
Orlando bought a new couch for 2,736, using the furniture store's finance plan. He will pay $114 a month for 24 months. Which equation can Orlando use to find out how much money he still owes after each month of the plan?
Answer:
[tex]y = 2736 - 114x[/tex]
Step-by-step explanation:
It is given that the cost of the couch was $2,736. Orlando bought that couch using furniture store's finance plan. The plan says that he is supposed to pay $114 per month for a period of 24 months.
we are asked to determine the equation which can determine the total amount still due on orlando after x number of months.
Let the total number of month we are calculating = x
Payment per month = $114
Hence payment made in x months = $114x
Hence payment still owned by Orlando = $2736-$114x
Above equation gives us the dues on Orlando

Two thirds of the employees at an office stated that they preferred soft cookies over crispy cookies. More than 36 employees stated their preference. Ren was asked to write, solve, and graph an inequality to find the number of employees working at the office. His work is shown below.
Answer:
Step 3 is wrong, he used the wrong circle
Step-by-step explanation:
To determine the minimum number of employees, solve the inequality 2/3 x > 36 to find x > 54. In Miguel's cookie choice, the events are dependent. According to the law of large numbers, probabilities stabilize as the number of trials increases.
Explanation:The question involves solving and graphing an inequality to find the minimum number of employees in an office based on their preferences for soft cookies. Since two thirds prefer soft cookies and more than 36 employees stated their preference, we can write this as an inequality where x represents the total number of employees: 2/3 x > 36. To solve for x, we multiply both sides of the inequality by 3/2, giving us x > 54. This tells us that there must be more than 54 employees in the office.
To graph the inequality, we would draw a number line, plot a point just above 54, and shade to the right to indicate all the numbers that are greater than 54. The question of dependent probabilities relates to Miguel's cookie selection where each choice affects the next; the events are not independent. Finally, the law of large numbers indicates that as the number of trials n increases, the experimental probabilities tend to get closer to the theoretical probabilities.
a triangular plot of land has boundary lines 45 meters, 60 meters, and 70 meters long. the 60 meter boundary line runs north-south. Is there a property for the boundary line that runs east-west
No, there is no property for the boundary line that runs east-west.
Explanation:No, there is no property for the boundary line that runs east-west. This is because if we have a triangle with side lengths 45 meters, 60 meters, and 70 meters, and the 60 meter side runs north-south, then the other two sides must be at an angle to the north-south line. It is not possible for one of the sides to be parallel to the north-south line (east-west) because that would create a rectangle rather than a triangle.

What is the missing reason in the proof?
A. vertical angles theorem
B. alternate exterior angles theorem
C. converse corresponding angles theorem
D. converse alternate interior angles theorem
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Given: g ∥ h and ∠2 ≅ ∠3
Statements Reasons
1. g || h 1. given
2. ∠1 ≅ ∠2 2.corresponding angles theorem
3. ∠2 ≅ ∠3 3. given
4. ∠1 ≅ ∠3 4. transitive property
5. e || f 5. Converse alternate interior angles.
As we know that if alternate angles are equal then two lines would be parallel using converse alternate interior angles.
Hence, Option 'D' is correct.
