Multiply the first term.
[tex]x \times {x}^{2} = {x}^{3} [/tex]
Multiply x by everything on the right, dont do x squared we already done that.
[tex]x \times - 3x = - 3 {x}^{2} [/tex]
[tex]x \times - 1 = - x[/tex]
Multiply 2 by everything on the left expect -1. ( that our next step).
[tex]2 \times {x}^{2} = 2 {x}^{2} [/tex]
[tex]2 \times - 3x = - 6x[/tex]
Multiply the last term, 2 and -1.

Quadrilateral CDEF is dilated by a scale factor of į to form quadrilateral C'D'E'F'.
What is the measure of side EF?
Answers
Given:
CDEF is dilated by a scale factor of [tex]\dfrac{3}{4}[/tex] to form the quadrilateral C'D'E'F'.
To find:
The measure of side E'F'.
Solution:
If a figure is dilated by a scale factor of k, then the side of dilated figure is k times of corresponding side of original figure.
CDEF is dilated by a scale factor of [tex]\dfrac{3}{4}[/tex] to form the quadrilateral C'D'E'F'. So,
[tex]E'F'=\dfrac{3}{4}\times EF[/tex]
From the given figure it is clear that [tex]EF=12[/tex]. So,
[tex]E'F'=\dfrac{3}{4}\times 12[/tex]
[tex]E'F'=9[/tex]
Therefore, the measure of side E'F' is 9 units.

In a graph, you have two points, Y, and X. In math, you will see (x,y) and in division, y/x = rise/run. In this case, Y is the rise, or the standing line, and the run (x), is the sitting line. Rise over run means 2/4, or, 1/2. Hope this helps :)
In the case of (x,y) on a graph chart, the dot would be (4,2) on the graph.
Determining the sale price of a home is an important task for city assessors, as it helps the city project future tax revenue. Regression models using the physical characteristics of a home to predict the sale price is standard practice for many assessors. A random sample of 724 homes sold in Ames, Iowa, between 2006 and 2010 was obtained to build such a model for the city of Ames. The assessor considered the following variables in their initial model:
Variable Description
LotArea Lot size (in thousands of square feet)
LivingArea Living space (in thousands of square feet)
Bedrooms Number of bedrooms
Rooms Number of rooms
Fireplaces Number of fireplaces
Bath Number of bathrooms
Age Age of the home (in years)
Price Sale price of the home (in thousands of dollars)

A helicopter hovers 1100 The above a small island the figure shows the angle of depression from the helicopter to point P is 46° how far off the coast to the nearest foot is the island?
Answers
Answer:
1232 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.

A gas measuring 525 mL is collected at 104.66 kPa. What volume does this gas
occupy if the pressure is increased by 25 kPa?
Answers
Recall the ideal gas law:
P V = n R T
where
P = pressure
V = volume
n = number of gas molecules
R = ideal gas constant
T = temperature
If both n and T are fixed, then n R T is a constant quantity, so for two pressure-volume pairs (P₁, V₁) and (P₂, V₂), you have
P₁ V₁ = P₂ V₂
(since both are equal to n R T )
Solve for V₂ :
V₂ = P₁ V₁ / P₂ = (104.66 kPa) (525 mL) / (25 kPa) = 2197.86 mL

connie poured 200 milliliters of juice into a glass from a juice carton. She then poured 225 milliliters into a second glass. What is the final change in the volume of the carton?
Answers
Answer:
A reduction of 450ml
Step-by-step explanation:
Given
[tex]V_1 = 200ml[/tex] -- To glass 1
[tex]V_2 = 250ml[/tex] --- To glass 2
Required
The final change to the carton
To do this, we simply add V1 and V2
So, we have:
[tex]Total = V_1 + V_2[/tex]
[tex]Total = 200ml + 250ml[/tex]
[tex]Total = 450ml[/tex]
This implies that the changes is a reduction of 450ml

You saved $180 on your new laptop because you bought it online. If this was a 20% savings from the original price, find the original cost of the laptop.
Answers
Answer:
$900
Step-by-step explanation:
$180 divided by 0.20 is $900
A percentage is a way to describe a part of a whole. The original cost of the laptop is $900.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the original cost of the laptop be represented by x.
Given that you saved $180 on your new laptop, which is a 20% saving from the original price. Therefore, the percentage can be written as,
20% of original price = $180
(20/100) × x = $180
x = ($180×100)/20
x = $900
Hence, the original cost of the laptop is $900.
