Factor expression 12p-28 factored using GCF is?
Answer:
4(3p - 7)
Step-by-step explanation:
First find the factors of 12 and 28:
12: 1, 2, 3, 4, 6, 12
28: 1, 2, 4, 7, 28
Notice any common factors: 1, 2, 4
Now, out of these factors, 4 is the GCF since it is the greatest common factor, so divide 12 and 28 by 4:
12/4 = 3. 28/4 = 7.
Hence, 12p-28 = 4(3p - 7)

The sum of an integer and seven times next consecutive odd integers -26 find the value of the lesser integer
Answer:
-5
Step-by-step explanation:
Let n = an integer
Let (n+2) = the next consecutive odd integer
n + 7( n + 2) = -26 Distribute the 7
n + 7n + 7(2) = -26
n + 7n + 14 = -26 Combine like terms
8n +14 = -26 Subtract 14 from both sides
8n + 14 - 14 = -26 -14
8n = -40 Divide both sides by 8
n = -5
The next consecutive odd integer would be -3
Consecutive just means the next number.

What is the axis of symmetry of the function f x =-( x 9 )( x 21?
The axis of symmetry of the function f(x) = -( x 9 )( x 21) is x = 15.
The axis of symmetry of a parabola is a line that divides the parabola into two exact mirror images. In this case, the parabola is defined by the quadratic function f(x) = -(x-9)(x-21). To find the axis of symmetry, we can take the average of the x-coordinates of the two solutions, which are 9 and 21. The average of 9 and 21 is 15, so the axis of symmetry is x = 15. This means that the parabola is symmetrical about the line x = 15, and the vertex of the parabola is located at the point (15,0).

Mr. Johnson needs to determine how many square meters of grass they need to buy for their yard.
2 m
5 m
9 m
10 m
How much grass will he need to buy to cover his yard?
Answer:
Amount of grass needed (In square meter) = 34 meter²
Step-by-step explanation:
Divide given shape into rectangle and trapezium
Given:
Width of rectangle = 2 m
Length of rectangle = 5 m
Height of parallelogram = 9 - 5 = 4 m
Base of parallelogram = 10 m
Opposite site of parallelogram = 2 m
Find:
Amount of grass needed (In square meter)
Computation:
Amount of grass needed (In square meter) = Area of rectangle + Area of parallelogram
Amount of grass needed (In square meter) = (l x b) + (1/2)(sum of parallelogram)(height)
Amount of grass needed (In square meter) = (5 x 2) + (1/2)(2 + 10)(4)
Amount of grass needed (In square meter) = 10 + (1/2)(12)(4)
Amount of grass needed (In square meter) = 10 + 24
Amount of grass needed (In square meter) = 34 meter²
Which expression can be used to determine the total weight of a box that by itself weighs 0. 3 kilogram and contains p plaques that weigh 3. 2 kilograms each?
The expression is t = 0.3 + 3.2p, where t is the box's overall weight and p is the number of plaques it contains.
Let's review the data given to us to properly respond to the question:
Weight of a box by itself = 0.3 kg
Weight of a plaque = 3.2 kg
The expression can be used to determine the total weight of the box :
We shall use the following phrase to respond to the query:
Total weight of the box in kg = t

What is Bar graph?Using rectangular bars with heights or lengths proportionate to the values they represent, a bar chart or bar graph displays categorical data. Both a vertical and a horizontal bar plot are possible. A column chart is another name for a vertical bar graph.
There are a few steps to follow when plotting a graph:
Identify the variables in the problem and choose which one to plot on the x-axis and which one to plot on the y-axis.Determine the range of values for each variable. This will help you decide how big to make the scales on the x and y-axis.Choose a scale for each axis. The scale should be such that all the points in the problem can be plotted on the graph. A typical scale is to have equal intervals between each tick mark on the axis.Plot the points on the graph by locating their x-coordinate and y-coordinate on the x-axis and y-axis, respectively, and connecting them with a dot.Draw the x- and y-axes and label them with the appropriate units and ranges. Be sure to include a label on the graph itself so that it's clear what the graph represents.Plot any lines or curves that are also a part of the problem. This could be a line of best fit, a linear regression line, a polynomial function or any other lines or curves that the problem calls for.Once you finished with the line/curve, it is a good practice to give the graph a title and to label the axis with the units used.Lastly, review the graph and ensure that it is accurate and clearly presents the information from the problem.To know more about graph visit:

Let the missing side be x.
Use Pythagorean:
x² + 8² = 16²x² = 256 - 64x² = 192x = √192x = 13.9 (rounded to the nearest tenth)Cedro bought five games and eight songs for a total cost of $22. 87. Benita bought seven songs and four games for a total cost of $18. 89. The cost of their purchases can be represented by the following equations: 5g + 8s = 22. 87 and 7s + 4g = 18. 89 where g is the cost of each game and s is the cost of each song purchased. What was the cost of each game and each song purchased?
The purchasing cost of each game costs $1.55 and each song costs $1.89 according to the given equation.
What are variables?A variable is a symbol or character that represents a value or set of values in mathematics and computer programming that can change and take on different values depending on the context.
The given problem can be solved using a system of equations.
The first formula, 5g + 8s = 22.87, represents the total cost of games and songs purchased by Cedro.
The second formula, 7s + 4g = 18.89, represents the total cost of games and songs purchased by Benita.
5g = 22.87 - 8s
g = (22.87 - 8s)/5.
We can now substitute this expression for g into the second equation and solve for s. So we have:
7s + 4((22.87 - 8s) / 5) = 18.89
On expanding and solving this equation for s we get:
7s + (91.48 - 32s) = 18.89
32s + 7s = 73.59
39s = 73.59
s = 1.89
By substituting the value of s into the equation 5g = 22.87 - 8s gives
5g = 22.87 - 8(1.89)
5g = 22.87 - 15.12
5g = 7.75
g = 1.55

Let f(x) = ax^n + bx^{n-1} + ... + z be a polynomial with integer coefficients and degree n>1. According to the theorem of Tchebychev, the maximal number of consecutive integers belonging to the sequence f(1),f(2),f(3),... is bounded by the expression 2*sqrt(n*|a|), where a is the coefficient of the highest degree term of f(x).
For example, let f(x) = 3x^3 + 4x^2 - 5. The coefficient of the highest degree term is 3, and the degree of the polynomial is 3. Therefore, the maximal number of consecutive integers belonging to the sequence f(1),f(2),f(3),... is 2*sqrt(3*|3|) = 6.
