The prime factorizations of 54 and 72 are shown below. Prime factorization of 54: 2, 3, 3, 3 Prime factorization of 72: 2, 2, 2, 3, 3 Using the prime factorizations, what is the greatest common factor of 54 and 72
1.2'3
2. 2' 3'3
3.2'2' 3'3
4.2'2'2'3'3'3
Step-by-step explanation:
54 = 2 * 3³
72 = 2³ * 3²
To find the GCF of 54 and 72,
we find the highest common powers of their prime factors.
Highest common power for 2: 2
Highest common power for 3: 3²
Hence GCF of 54 and 72 = 2 * 3².
The answer is Option 2.

Eduardo is painting a rectangular wall that is 96 inches high and 110 inches long. What is the area of the wall?
Here the height and length are the sides of the rectangular wall and we have to find the area.
Area of rectangle is given by:
[tex] = l \times b[/tex]
where l is the length and b is the breadth/width according to the question. Plugging the given values:
[tex] = 110 \times 96 \: {inch}^{2} [/tex]
[tex] = 10560 \: {inch}^{2} [/tex]
Hence:-The area of the wall is 10560 inch²

Someone help me do this please. I included a picture.
Answer:
52° and 128°
Step-by-step explanation:
The sum of the angles in a triangle is 180°
So to find the angles, the easiest thing to do is to use that fact.
There is one angle missing in the triangle shown, so to find it you need to subtract (5x-2)° from 180° since the angle is located on a line.
Simplifying that, you get 180°-(5x-2)°.
Now you can use the fact at the top of these instructions.
So you get the equation: 180°=2x°+76°+180°-(5x-2)°
Solving this equation, you get x=26
Plug x into the values that have x in the picture, and you get 52° and 128°

Answer: See explanation
Step-by-step explanation:
1. (x + 6)(x - 4)
x (x - 4) + 6 (x - 4)
x² - 4x + 6x - 24
x² + 2x - 24
2. (2x + 5)(x - 3)
2x (x - 3) + 5 (x - 3)
2x² - 6x + 5x - 15
2x² - x - 15
3. (3x + 2)(2x + 5)
3x (2x + 5) + 2 (2x + 5)
6x² + 15x + 4x + 10
6x² + 19x + 10
4. (2x - 1)(x - 5)
2x (x - 5) + -1 (x - 5)
2x² - 10x + -x + 5
2x² - 10x - x + 5
2x² - 11x + 5

What is the difference between 3 more than 1/3 and 3
Answer:
Step-by-step explanation:
3 more than 1/3 represents 3 + 1/3 Which would equal 3 and 1/3 or 10/3. This is different than 3 since it equals 9/3. They don’t equal each other due to it being 3 added to 1/3

Solve the system algebraically.
y = – 4x + 6
y = – 4x + 5
Answer:
We conclude that -1 = 0 is false, therefore the system of equations has no solution.
Step-by-step explanation:
Given the system of equations
y = – 4x + 6
y = – 4x + 5
solving the system of the equations
[tex]\begin{bmatrix}y=-4x+6\\ y=-4x+5\end{bmatrix}[/tex]
Substitute y = -4x+5
[tex]\begin{bmatrix}-4x+5=-4x+6\end{bmatrix}[/tex]
Refine – 4x + 5 = – 4x + 6
-1 = 0
FALSE!
NO SOLUTION!
We conclude that -1 = 0 is false, therefore the system of equations has no solution.

Juan has $67 in $5 and $1 bills. If has 19 bills in all, how many $1 bills does he have?
Juan have 7 bill for $1 bills.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Juan has $67 in $5 and $1 bills.
And, He has 19 bills in all.
Now, Let number of $1 bills = x
And, Number of $5 bills = y
Here, Juan has $67 in $5 and $1 bills.
So, We get;
⇒ x + 5y = 67 .. (i)
And, He has 19 bills in all.
So, We get;
⇒ x + y = 19
⇒ x = 19 - y .. (ii)
Substitute the value of x from (ii) in (i), we get;
⇒ x + 5y = 67
⇒ 19 - y + 5y = 67
⇒ 19 + 4y = 67
⇒ 4y = 67 - 19
⇒ 4y = 48
⇒ y = 12
And, from (ii),
⇒ x = 19 - y
⇒ x = 19 - 12
⇒ x = 7
