Factor as the product of two binomials. 36+12x+x^2=
Answer:
(6 + x)(6 + x) = (6 + x)²
Step-by-step explanation:
Given
36 + 12x + x²
Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (+ 12)
The factors are + 6 and + 6, since
6 × 6 = 36 and 6 + 6 = 12, thus
36 + 12x + x² = (6 + x)(6 + x) = (6 + x)²
Find the slope of the line that passes through the
points
(3, - 2)
and
(-2,5).
Answer:
The slope would be 7/5
Step-by-step explanation:
The slope is 7/5 because you can calculate slope by dividing the change in the y-value between two points over the change in the x-value. (y-y/x-x) you would just plug in the the points for X and Y, 5-(-2)/3-(-2) and you would get 7/5.

You have to find the width
Answer:
4 meters
Step-by-step explanation:
Area is length x width
28=7n where n is the unknown width
Solve for n and u get 4
Answer:
4 metres
Step-by-step explanation:
The garden is in the form of a rectangle. The area of a rectangle is denoted by A = lw, where l is the length and w is the width.
Here, we're given the length is l = 7 and the area is A = 28, so we can plug these into the formula:
A = lw
28 = 7 * w
Divide both sides by 7:
w = 28 / 7 = 4
Thus, the width is 4 metres.

C. 42 mm squared
D. 48 mm squared
Hello!
Answer:[tex]\boxed{ \bf The~area~of~the~shaded~region~is~B.~24 mm^2}[/tex]
______________________________________________________
Explanation:To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex](12 · 5)
A = [tex]\frac{1}{2}[/tex](60)
A = 30 mm²
Inner:
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex](4 · 3)
A = [tex]\frac{1}{2}[/tex](12)
A = 6

Answer:
Hey boss man, just add up all the sides! For example, just add 3.9+3.9+3.9! and if there is a line in the middle of a certain side, it means that it is congruent or the same as another side with a dash. For example, with number 2, the side without a measurement is congruent with the the side with measurement of 7mm! Hope this helps! You got this! :)
Step-by-step explanation:
A sphere is inscribed in a cube with a surface area of 216 square centimeters. What is the volume of the sphere? Round your answer to the nearest whole number.
Answer: 113.04 cm^3
Step-by-step explanation:
The surface area of a cube is:
S = 6*L^2
then:
216 = 6*L^2
216/6 = L^2
L = √(36) = 6
So the length of the side of this square is L = 6cm
Then the diameter of the sphere is also 6 cm, and the radius is half the diameter, so the radius is 3cm.
Now the volume of a sphere is:
V = (4/3)*pi*r^3 = (4/3)*3.14*3^3 = 113.04 cm^3
After eating dinner at a restaurant, Lucy's bill before tax is $48.00. The sales tax rate is 8%. Lucy decides to leave a 20% tip for the waiter based on the pre-tax amount. How much money will Lucy pay total, including tax and the tip?
Answer:
$61.44
Step-by-step explanation:
Both the tip and the tax are based on the original amount ($48).
To find the amounts, first change the percents to decimals.
8% = 0.08
20% = 0.20
Then, multiply the decimals by the original amount.
48 × 0.08 = 3.84
48 × 0.20 = 9.60
Next, add up the original amount, the tax, and the tip to find the total money spent by Lucy.
$48 + $3.84 + $9.60 = $61.44
The total amount spent is $61.44.
Lucy pay total amount of $61.44, including tax and the tip.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Both the tip and the tax are based on the original amount ($48).
To determine the amounts, first change the percents to decimals.
8% = 0.08
20% = 0.20
Now multiply the decimals by the original amount.
48 × 0.08 = 3.84
48 × 0.20 = 9.60
Next, add up the original amount, the tax, and the tip;
$48 + $3.84 + $9.60 = $61.44
The total amount spent will be $61.44.

Daniel drove from his house to his office. The graph show the distance Daniel had left to travel after for t driving
Answer:
Daniel office is located 20 miles from his house and it took Daniel 25 minutes to drive that distance.
Step-by-step explanation:
Since the graph shows the distance from his house to his office as a function of driving time, then when the driving time is equal to "0", it means that he didn't left his house yet and that is the distance from his house to his office. On the graph this is the point that crosses the "y" axis, 20 miles. When he arrives at his office, then the distance is equal to "0", since he already arrived at his destination. This happens when the graph crosses the "x" axis, which happens on the 25 min mark. So:
Daniel office is located 20 miles from his house and it took Daniel 25 minutes to drive that distance.

The two-way frequency table below shows data on behavior of students and the use of positive phone calls home as an incentive for behavior for a group of students at Lion's Lane Elementary School.
Complete the following two-way table of column relative frequencies.
(If necessary, round your answers to the nearest hundredth.)
Answer:
Step-by-step explanation:
Hello!
In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.
In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.
If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n
For the students that received the phone call:
n= 19 + 9= 28
The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68
The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32
For the students that didn't receive the phone call:
n= 8 + 6= 14
The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57
The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43
