The Greatest Common Factor of 22ab2c2 and 40a3c2 is 2ac2, found by identifying the highest power of each variable and number that divides the coefficients 22 and 40.
Explanation:When finding the Greatest Common Factor (GCF) we need to look for the highest power of each variable and number that appears in all the terms. In the terms 22ab2c2 and 40a3c2, the GCF will consists of the highest power of each variable found in both terms, and the highest number that divides both 22 and 40.
To find the GCF you need to divide both 22 and 40 by common factor. The highest number that divides 22 and 40 is 2. For the variables, the lowest power of 'a' and 'c' in both terms is a and c2, respectively. 'b' is not in both terms, so we omit it. So, the GCF of 22ab2c2 and 40a3c2 is 2ac2.

Which polygons are congruent?
Select each correct answer.
The required pairs of triangles in A and D are congruent triangles.
What are congruent triangles?Congruent triangles are two triangles that have the same shape and size. In other words, they are identical in every way, including their angles and side lengths. When two triangles are congruent, their corresponding sides and angles are equal.
Here,
Congruent triangles are important in geometry because they have many useful properties and can be used to solve a variety of problems. For example, if two triangles are congruent, then any corresponding parts (such as their altitudes, medians, or angle bisectors) will also be congruent. This can be helpful in finding missing side lengths or angles of a triangle.
Thus, from the above definitions Pairs of triangles in A and D are congruent triangles.

How many 4-digit numbers can you write if you cannot use any other digits except 0, 1, and 2?
There are 54 possible 4-digit numbers that can be created using only the digits 0, 1, and 2, considering that the first digit cannot be 0 and each position has a limited selection of digits.
Explanation:To determine the number of 4-digit numbers that can be written using only the digits 0, 1, and 2, we must take into account that a 4-digit number cannot start with 0, which leaves us two choices for the first digit (either 1 or 2). For the subsequent three digits, we have three choices each (0, 1, or 2). Therefore, the total number of 4-digit combinations is obtained by multiplying the number of choices for each digit's position.
The explanation you provided is correct, and the calculation is accurate. There are indeed 54 possible 4-digit numbers that can be created using only the digits 0, 1, and 2, considering the given conditions.
To summarize:
- The first digit has 2 possible choices (1 or 2).
- Each of the next three digits has 3 choices (0, 1, or 2).
So, the total number of 4-digit combinations is obtained by multiplying the number of choices for each digit's position:
\[2 \times 3 \times 3 \times 3 = 54.\]
Therefore, there are 54 possible 4-digit numbers that can be created following the given conditions.
The first digit has 2 possible choices, and each of the other three positions has 3 choices, which gives us a total of:
2 × 3 × 3 × 3 = 54 possible 4-digit numbers using the digits 0, 1, and 2.
the parabola y=x^2 is shifted up by 4 units
By rigid transformations, the image of the parabola y = x² is equal to parabola y = x² + 4.
How to determine the image of a parabola
In this problem, we need to determine the image of a parabola by means of a rigid transformation known as vertical translation:
y = f(x) → y = f(x) + k, where k represents a translation upwards and f(x) is the original function.
If we know that f(x) = x² and k = 4, then the image of the function is:
f(x) = x² + 4

Justine draws a square with an area of 150 square centimeters. What is the approximate length, in centimeters, of one side of the square? -2 cm -11 cm -12 cm -13 cm
The approximate length is 12 centimeters, of one side of the square which is the correct answer would be an option (C).
What is the square?A square is a closed two-dimensional object with four equal-length sides and all interior angles of exactly 90 degrees.
The diagonal of the square is the distance between two vertices on opposing sides. A square has two diagonals of equal length.
We have been given that Justine draws a square with an area of 150 square centimeters.
The area of the square = (length of the side)²
150 square centimeters = (length of the side)²
Length of the side = √(150)
Length of the side = 12.24744
Rounded the nearest hundredth and we get
Length of the side = 12.24 centimeters
Therefore, the approximate length is 12 centimeters, of one side of the square.

How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18/ 2
A)no solutions
B)one solution
C)two solutions
D)infinitely many solutions
Answer: The correct option is A.
Explanation:
The given equation is,
[tex]4(x+5)-5=\frac{8x+18}{2}[/tex]
Multiply both sides by 2.
[tex]2[4(x+5)-5]=\frac{8x+18}{2}[/tex]
[tex]8(x+5)+2(-5)=8x+18[/tex]
[tex]8x+40-10=8x+18[/tex]
[tex]8x+30=8x+18[/tex]
Subtract both sides by 8x.
[tex]30=18[/tex]
This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
Answer:
Option A is correct
No solutions
Step-by-step explanation:
The distributive property says that:-
[tex]a \cdot (b+c) = a\cdot b+ a\cdot c[/tex]
Given the equation:
[tex]4(x+5)-5 = \frac{8x+18}{2}[/tex]
Using distributive property we have;
[tex]4x+20-5 = \frac{8x+18}{2}[/tex]
⇒[tex]4x+15= \frac{8x+18}{2}[/tex]
Multiply both sides by 2 we have;
[tex]8x+30 = 8x+18[/tex]
Subtract 8x from both sides we have;
[tex]30=18[/tex] False.
For any value of x, there is no solutions for the given system of equation
Therefore, No solution can be found for the linear equation

A group of 11 people are going to the movies one Saturday. Adults' tickets cost $11.50 each and children's tickets cost $7.25 each. If the total cost for admission to the movies is $105.25, how many children attended the movie?
Answer: 5
Step-by-step explanation:
Let x be the number of adults and y be the number of children going to the movies one Saturday.
Given : A group of 11 people are going to the movies one Saturday.
[tex]x+y=11----------------(1)[/tex]
Adults' tickets cost $11.50 each and children's tickets cost $7.25 each.
The total cost for admission to the movies is $105.25.
i.e. [tex]11.50x+7.25y=105.25-----------------(2)[/tex]
Multiply equation (1) by 11.5 , we get
[tex]11.5x+11.5y=126.5---------------------(3)[/tex]
Subtract equation (2) from (3), we get
[tex]4.25y=21.25\\\\ y=\dfrac{21.25}{4.25}=5[/tex]
Put value of y= 5 in (1), we get
[tex]x+5=11\\\\ x=11-5=6[/tex]
Hence, 5 children attends the movie.
