The regression solved shows that the predicted selling price for a home that is 12 years of age is $443747.

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:

Sample response: Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

Answer:

lateral area = 1892.1 m²

Step-by-step explanation:

The lateral surface area of the square based pyramid is required.

lateral surface area = 1/2 × perimeter × slant height

we have to find the slant height using Pythagoras theorem

base = 35

height = 27.03

slant height² =  17.5² + 27.03²

slant height² = 1036.8709 + 424.36

slant height² = 1461.2

slant height = √730.61

slant height = 27.0297983714

slant height ≈ 27.03 m

lateral area = 1/2 × perimeter × slant height

lateral area = 1/2 × 35 × 4 × 27.03

lateral area = 3784.200/2

lateral area = 1892.1 m²

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.

Answer:

so basiclly a monkey can not turn into a monkey so they are real monkeys

Step-by-step explanation:

The solution of the given expression  (x − 2)(x 10) = 13 are x=3 or x=-11. So the option A is correct.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

(x-2)(x+10) = 13

Subtract 13 from both sides

x²+8x-20-13=13-13

x²+8x-33=0

Factorized

(x-3)(x+11)=0

x-3=0 or x+11= 0

x=3 or x=-11

Thus, The answer is A

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.

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 )

Answer:

35 units ^2

Step-by-step explanation:

First, draw lines or count how many units are between each point. Don't go diagonal, just up/down or left/right, like from point B to point A.

So I counted 5 units from point B to A, 5 units from C to D, 7 units from A to D, and 7 units from B to C.

Now, you choose two sides - one that goes up/down and one that goes left/right. This is your base and your height.

So you should have 5 and 7. Now, the equation of a rectangle is base times height (b* h) so you multiply 5 and 7 together to get your answer, 35 units ^2

I hope this helps :)

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
