Answer:
8x + 20 or 4(2x + 5)
Step-by-step explanation:
Perimeter equals length + width times 2. If the width is 3x + 4, and the length is x+6, you first add 3x + 4 + x + 6. You first add the like terms, 3x and x, which is 4x. Now you add 4 and 6, which equals ten. Now, you get 4x + 10. Lastly, you have to multiply it by two. 4x + 10 + 4x + 10 equals to 8x + 20. You add up the like terms 4x and 4x and 10 and 10, to get the total of 8x + 20.

A rectangle has sides measuring (2x + 7) units and (5x + 9) units.
Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points)
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
Answer:
A: 10x^2 +53x +63 B: degree 2; quadratic trinomial C: the result of the multiplication of polynomials is a polynomial
Step-by-step explanation:
Part A:
The area is the product of length and width. The distributive property is useful for simplifying the expression.
A = LW
A = (2x +7)(5x +9) = 2x(5x +9) +7(5x +9)
A = (10x^2 +18x) +(35x +63)
A = 10x^2 +53x +63 . . . . area expression
Part B:
The highest power of x is 2. There are 3 terms. A degree-2 polynomial is called a "quadratic." A 3-term polynomial is called a "trinomial."
degree 2
quadratic trinomial
Part C:
In part A we multiplied two polynomials and came up with a result that is a polynomial. This suggests polynomials are closed with respect to multiplication.

A. Set B is an exponential function and the values increase at a faster
rate than Set A.
B. Set A is a linear function and the values increase at a faster rate
than Set B.
O C. Set A is a linear function and the values increase at the same rate
as Set B.
D. Set B is an exponential function and the values increase at the
same rate as Set A.
Answer:
A is the correct answer
Step-by-step explanation:
The reason is that in set B, you are multiplying by 5 at each step, in set A you are adding 25 at each step which is clearly slower. to check this out try to determine the 10th value of the two functions

7x – y = 7
7x2 – y = 7
(0, 7) and (0, –7)
(1, 0) and (0, –7)
(3, 14) and (0, –7)
(4, 14) and (–1, 10)
Answer:
2nd option
Step-by-step explanation:
7x - y = 7 ( multiply through by - 1 )
- 7x + y =- 7 ( add 7x to both sides )
y = 7x - 7 → (1)
7x² - y = 7 → (2)
substitute y = 7x - 7 into (2)
7x² - (7x - 7) = 7 ← distribute parenthesis on left side
7x² - 7x + 7 = 7 ( subtract 7 from both sides )
7x² - 7x = 0 ← in standard form
7x(x - 1) = 0 ← in factored form
equate each factor to zero and solve for x
7x = 0 ⇒ x = 0
x - 1 = 0 ⇒ x = 1
substitute these values into (1) for corresponding values of y
x = 0 : y = 7(0) - 7 = 0 - 7 = - 7 ⇒ (0, - 7 )
x = 1 : y = 7(1) - 7 = 7 - 7 = 0 ⇒ (1, 0 )

Convert the following into metres.
A- 22cm
B- 180km
C-300mm
A) 22cm
( divide the length value by 100)
22/100 which gives you:
=0.22m
B) 180km
( multiply the length value by 1000)
180×+100 which gives you:
=180000m
C) 300mm
( divide the length value by 1000)
300/1000 which gives you:
=0.3m
A home appraisal company would like to develop a regression model that would predict the selling price of a house based on the age of the house in years (Age), the living area of the house in square feet (Living Area) and the number of bedrooms (Bedrooms). The following Excel output shows the partially completed regression output from a random sample of homes that have recently sold. The predicted selling price for a home that is 12 years of age, has 2,500 square feet of living area, and has four bedrooms is ________
The regression solved shows that the predicted selling price for a home that is 12 years of age is $443747.
How to compute the value of the home?From the complete information, the regression equation is given as:
y = 108597.37 - 580.687 × age + 86.82 × living areas + 31261.9127 × bedroom
Therefore, the predicted selling price will be:
= 108597.37 - 580.687 × 12 + 86.82 × 2500 + 31261.9127 × 4
= $443747
In conclusion, the selling price is $443747.

Answer:
4x³ + 12x²
Step-by-step explanation:
I assume the denominators are x² and 4x although that is not what you wrote.
x² = x² (already factored)
4x² + 12x = 4x(x + 3)
LCD = 4 × x² × (x + 3)

Nicole is on her way home in her car. She has driven 10 miles so far, which is one-half of the way home. What is the total length of her drive?
Answer:
20 miles
Step-by-step explanation:
10 x 2 = 20
10 miles is half the drive so you'd just multiply it by 2 and that would be the full amount of miles home.
Answer:
The total length of Nicol’s drive would be 20 miles.
If The first half of her trip takes 10 miles then the second half would have an equal number of miles. 10x2=20
You would use 10 two times because 1/2+1/2=1.
Therefore the total amount of miles Nicole will travel will be 20.

The chart below shows the results of survey taken by a movie theater. The theater asked what genre the mover goers preferred to see. If the theater owner asked 100 people, how many people would prefer Drama? Round to the nearest whole number
Answer: Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.
Step-by-step explanation:
Theater is a place where the movies are shown in big screens and Speakers are used for the clear audio of the movie.
In a theater there will be 3 to 4 shows for a movie or different movie.
Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.
Consider a ticket cost of 200rs. For 100 people in a show ,
Cost = 200 × 100
Cost = 20,000.
Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

The area of a triangle is 106 square feet. The base is twice the height. Find the height.
Answer:
The height is [tex]\sqrt{106}[/tex] feet
Step-by-step explanation:
First, lets assign and categorize the information given to us:
Area = 106 [tex]ft^{2}[/tex]
b = 2h (Base is twice the height)
Next, lets look at the formula for the area of a triangle:
Area = [tex]\frac{1}{2} bh[/tex]
Then, lets substitute the given information and solve:
106 = [tex]\frac{1}{2}[/tex] * 2h * h
106 = [tex]h^{2}[/tex]
[tex]\sqrt{106}[/tex] feet = h

Answer:
For no values of x.
Step-by-step explanation:
A function is increasing when its graph is sloping upwards.
Conversely, a function is decreasing when its graph is sloping downwards.
From the given graph, we can see that it is sloping downwards at all x values. In other words, it is always decreasing and never increases.
Therefore, for no values of x is the graph increasing.
