Answer:
[tex] {x}^{2} + 9x + 20[/tex]
Step-by-step explanation:
1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.
[tex] {x}^{2} + 5x + 4x + 20[/tex]
2) Collect like terms.
[tex] {x}^{2} + (5x + 4x) + 20[/tex]
3) Simplify.
[tex] {x}^{2} + 9x + 20[/tex]
Therefor, the answer is x² + 9x + 20.

Answer:
10.3
Step-by-step explanation:
The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.
[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]
We find the square root of both sides to find the value of c.
10.295 ≈ c
Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3
A circular sector has a central angle of π6 radians and a radius of 9 ft.
What is the area of the sector?
Use 3.14 for pi. Round your answer to the nearest tenth.
Enter your answer in the box.
area = ft2
Answer:
[tex] \approx \: 21.2 \: {ft}^{2} [/tex]
Step-by-step explanation:
[tex]central \: \angle = \frac{\pi ^{c} }{6} = 30 \degree \\ \\ area \: of \: the \: sector = \frac{30 \degree}{360 \degree} \times \pi {(9)}^{2} \\ \\ = \frac{1}{12} \times 3.14 \times 81 \\ \\ = \frac{1}{12} \times 254.34 \\ \\ = 21.195 \: {ft}^{2} \\ \\ \approx \: 21.2 \: {ft}^{2} [/tex]
Answer:
given
π6radian=30°
radius r =9ft
the area of the sector=30°/360×π×r²
=30/360×22/7×9²=21.214ft²

One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45
Answer:
x=60, y= 60
x=100, y= 20
x=40, y=80
Step-by-step explanation:
Triangles add up to 180 degrees. The ones above added to 60 equal 180.
60+60+60=180
100+20+60=180
40+80+60=180

Step-by-step explanation:
To convert decimal number 639 to quinary, follow these steps:
Divide 639 by 5 keeping notice of the quotient and the remainder.Continue dividing the quotient by 5 until you get a quotient of zero.Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.Using the above steps, here is the work involved in the solution for converting 639 to quinary number:639 / 5 = 127 with remainder 4127 / 5 = 25 with remainder 225 / 5 = 5 with remainder 05 / 5 = 1 with remainder 01 / 5 = 0 with remainder 1Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :

Data was collected about the number of years of playing football and annual starting salaries in the NFL. The data can be summarized by the equation s=54x +0.5, where s is the starting salary, in millions, and x is the number of years playing football. According to this model, how much money does an NFL player make each year? Write your answer in millions. Here since nobody wants to answer something that will get your attention! GUYS, PLEASE HELP ME!
Answer and Step-by-step explanation:
The answer should be 54 million.
Plug in 1 for x, which you get 54.5.
Then you plug in 2 for x, which you get 108.5
Now, subtract the subtract the 1st one from the 2nd one.
108.5 - 54.5 = 54 (million)

Do the following set of points represent a function?Explain your answer (2,3),(3,8),(-1,4),(1,8)
Answer:
Yes.
Step-by-step explanation:
Yes.
To have a function, you cannot use the same value for an x-coordinate more than once. Here, each value of an x-coordinate is used only once, so it is a function.
Answer:
Yes.
Step-by-step explanation:
It is a many-to-one function. Both 3 and 1 map to 8.
2 maps to to 3 and -1 maps to 4 which is one-to-one.
There are no one to many mappings so it is a function.

The Davis family is going to reseed the grass in the backyard. Their yard is irregularly shaped with a cement patio and rectangular garden as shown below.
Given that the family will not need grass seed for the patio or the garden areas, what is the total area of the land will they be reseeding?
Answer:Answer:
1,482 square feet
Step-by-step explanation: Find total area - 37 x 46 = 1,702
Find area of patio and garden - 16 x 10 = 160 for the patio, 12 x 5 = 60 for the garden
Subtract from total area - 1702 - 160 = 1542, 1542 - 60 = 1,482 sq ft
Factor completely 49x2 − 9.

Describe two different ways to find the total area of the park.
Answer:
1. Combine the like terms from all 3 sections then subsite for X.
2. You can subsitue X in and solve the areas for each section, then adding up the 3 areas.
Step-by-step explanation:
The two ways to find the total area of the park are:
Add the Areas of Each Section
Use Geometric Shapes
Both methods should give us the same total area of 3x² + 175x + 1200 ft².
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Method 1:
Add the Areas of Each Section
We can find the total area of the park by adding the areas of each section. Therefore, the total area is:
Total Area = Game field + Picnic field + Recreation area
Total Area = (x² + 95x + 450) + (x² + 45x + 450) + (x² + 35x + 300)
Total Area = 3x² + 175x + 1200 ft²
Method 2:
Use Geometric Shapes
Another way to find the total area of the park is to use geometric shapes that represent each section.
We can see that the Game field and Picnic field have the same area of
x² + 95x + 450 ft², which we can represent as a rectangle.
The Recreation area has an area of x² + 35x + 300 ft², which we can represent as a triangle.
Therefore, the total area of the park is the sum of the areas of the rectangle and triangle.
Total Area = Area of Rectangle + Area of Triangle
Total Area = (x + 15)(x + 30) + (1/2)x(x + 35)
Total Area = 3x^2 + 175x + 1200 ft^2
Thus,
Both methods should give us the same total area of 3x² + 175x + 1200 ft².

Answer:
67.5 feet
Step-by-step explanation:
If 1 inch = 9 feet, and the model is 7.5 inches,
you just need to do 7.5 • 9 = 67.5 feet.
OR
7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5
63 + 4.5 = 67.5
*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet
