Which is a solution to (x − 2)(x 10) = 13? x = 3 x = 8 x = 10 x = 11
The solution of the given expression (x − 2)(x 10) = 13 are x=3 or x=-11. So the option A is correct.
What is a quadratic equation?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

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:
14 [m].
Step-by-step explanation:
1) in the square ABCD AC is diagonal, its length can be calculated as AB*√2;
2) the length of AB can be calculated:
AB=√Area(ABCD); ⇒ AB=√98;
Then
3) AC=√98*√2=14 [m].
Answer:
[tex]14\:m[/tex]
Step-by-step explanation:
ABCD is a square. (Given)
[tex] \implies \: A(square) = \overline{AB} ^{2} \\ \\ \implies \: 98 = \overline{AB} ^{2} \\ \\ \implies \: \overline{AB} = \sqrt{98} \\ \\ \implies \: \overline{AB} = \sqrt{ {7}^{2} \times 2} \\ \\ \implies \: \overline{AB} = 7\sqrt{ 2}\\\\\implies \overline{AC}= \overline{AB} \times \sqrt 2 \\\\\implies \overline{AC}= 7\sqrt{ 2} \times \sqrt 2\\\\\implies \overline{AC}= 14\: m[/tex]
The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with diameter 0.01 inch has a resistance of 10 ohms, what is the resistance of 140 feet of the same type of wire if its diameter is 0.01 inch
Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.

There are 239 people in the first 6 rows of a movie theater. If the same number of people are in the next 6 rows, about how many people are in the next 12 rows?
How do you do this??
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

The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.
What is additive inverse?The additive inverse of a number is the other number which when added to the initial number gives the output as zero.
As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.
The additive inverse of the complex number -8+3i will be,

Mrs. Bailey is knitting a striped blanket for her granddaughter. She made of the blanket pink, of the blanket green, and the rest
of the blanket was white. Which fraction represents the white part of the blanket?
A) 3/4 of the blanket
B) 5/8 of the blanket
C) 1/2 of the blanket
D) 3/8 of the blanket
...
Answer:
D) 3/8 of the blanket
Step-by-step explanation:
Adding up the pink and green parts, then subtracting it from 1 would yield the white area. Finding a common denominator gives: 2/8 + 3/8 which is 5/8. So 5/8 of the blanket is not white meaning that 3/8 of the blanket is white.

https://brainly.com/question/22560523
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.

The Louvre is an art museum in Paris. A glass square base pyramid sits in front of the entrance
to the museum. If the pyramid is 35 meters wide at the base and has a slant height of 27.03
meters, what is the minimum amount of glass needed to construct the pyramid? Find the Lateral
Area
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
