Answer:
(4x +5)
Step-by-step explanation:
The square of a binomial is ...
(a +b)² = a² +2ab +b²
We assume that the given trinomial is a perfect square, so we can find the terms of the squared binomial by looking at the square roots of the first and last terms:
√(16x²) = 4x
√25 = 5
So, our first choice of side length for the square is ...
s = (4x +5) . . . . . side length of the square
__
Using the above identity, we can verify that the square of this gives the right area:
A = s² = (4x +5)² = (4x)² +2(4x)(5) +5²
A = 16x² +40x +25 . . . . . . as required

Answer:
150 and -150
Step-by-step explanation:
For question number 2...
You started off with an energy level of 250 and something was added to make it 400.
To figure out what this "something" was, you simply subtract the numbers.
400 - 250 = 150
For question number 3...
You start off with 325 and end with 175. Here, the outcome is smaller or less than what you started with. So, you know that you took away a certain amount of energy. To figure that out, you again subtract.
325 - 175 = 150
To make the equation make sense, you would subtract 150.
So the answer would -150.

Suppose a binomial trial has a probability of success of 0.3, and 500 trials are performed. What is the standard deviation of the possible outcomes? Round
your answer to two decimal places.
O A. 10.25
OB. 8.94
O c. 6.71
D. 10.95
Answers
The standard deviation of the possible outcomes is to be considered as the 10.25.
Calculation of the standard deviation:Since there is a binomial trial has a probability of success of 0.3, and 500 trials are performed.
So here
q = 1 - P
= 1 - 0.3
=0.7
Now the standard devation be like
[tex]= \sqrt{500\times 0.3 \times 0.7}[/tex]
= 10.25
hence, The standard deviation of the possible outcomes is to be considered as the 10.25.

Complete the table for the equation y = x - 2. Then use the table to graph the equation.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]y = x-2[/tex]
comparing with the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
The slope of the line y = x-2 will be: m = 1The y-intercept of the line = b = -2Let us plug in some values
at x = 0, y = x-2 ⇒ y = 0-2 ⇒ y = -2
at x = 1, y = x-2 ⇒ y = 1-2 ⇒ y = -1
at x = 2, y = x-2 ⇒ y = 2-2 ⇒ y = 0
at x = 3, y = x-2 ⇒ y = 3-2 ⇒ y = 1
at x = 4, y = 4-2 ⇒ y = 4-2 ⇒ y = 2
Thus, the table of the equation y = x-2 becomes

Graph the line that passes through the two lines (1,5/2), (-1/2,-1/4)
Answers
Answer:
Image below
Step-by-step explanation:
Graph of a Line Given Two Points
We are given the points (1,5/2), (-1/2,-1/4).
A straight line is entirely defined by two points. We have to plot them and join them with a straight line ending in arrows.
The point (1,5/2) is converted to decimal as (1,2.5)
The point (-1/2,-1/4) is also converted to decimal: (-0.5,-0.25)
This helps to define the divisions of each axis and properly draw the line.
Please refer to the image below.
Solve the following system of equations graphically on the set of axes below.
Y=1/3x+6 y=-5/3x-6
Answers
Answer:
I can not solve it in the system of the image, but i will give you the graph so you can copy it, or at least see how it is done.
First, we have the lines:
y = (1/3)*x + 6
y = (-5/3)*x - 6
To graph these lines, you must find two points for the lines and then draw a line that connects the points.
To do it, you can evaluate each line in two different values of x, for example for the first line we can have:
y(0) = (1/3)*0 + 6 = 6 (then we have the point (0, 6))
y(3) = (1/3)*3 + 6 = 7 (then we have the point (3, 7))
And for the second line, we will have:
y(0) = (-5/3)*0 - 6 = -6 (then we have the point (0, -6))
y(3) = -(5/3)*3 - 6 = -11 (then we have the point (-3, -11))
Now with those points we can graph the lines, and the solution of the system of equation will be the point where the two lines intersect.
The graphs of the lines are shown below:
Where the grey line is the first one, and the green is the second.
In the graph, you can see that the lines intersect in the point (-6, 4)
Then the solution for the system is x = -6, and y = 4.

Answer:
9 cm.
Step-by-step explanation:
First, let's form an equation. We'll represent the final depth of snow on Cherry Street with the variable d. We'll represent the hours with the variable h.
10 - 1/3h = d
Now, you already know what h equals so you can replace h with 3 for 3 hours.
10 - 1/3(3) = d
1/3 * 3 = 1.
10 - 1 = d
10 - 1 = 9
Now, we know what d equals.
10 - 1/3(3) = 9.
Do NOT forget the unit of measurement in your final answer, cm. In the photo, it looks as though it has already been provided.
The final answer is 9 cm.

Answers
Answer:
$2.65Step-by-step explanation:
Let chocolate bar cost = c and blow pops cost = b
As per given we have equations below:
5c + 8b = 23.25 2c + 13b = 21.5513 times the first equation minus 8 times the second to eliminate b and find c:
13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55) 65c - 16c = 129.85 49c = 129.85 c = 129.85/49 c = 2.65Each chocolate bar costs $2.65
