prove that,
b) (a + b)2 = (−a − b)2
c) (a − b)2 = a2 − 2ab + b2
We will prove both of the identities by expanding the exponents, only in the first one we need to use a little trick that is multiplying by (-1)^2 = 1.
How to prove the identities?
Let's start with the first one:
(a + b)^2 = (- a - b)^2
We can start with the left side and write:
(a + b)^2 = (a + b)*(a + b)
Now, remember the rule of signs:
(-1)*(-1) = 1
So we can multiply by one the expression above and get:
(a + b)*(a + b) = (a + b)*(a + b)*1 = (a + b)*(a + b)*(-1)*(-1)
Now we can reorder the product to get:
(a + b)*(a + b)*(-1)*(-1) = (-1)*(a + b)*(-1)*(a + b) = (-a - b)*(-a - b) = (-a - b)^2
So we proved the first part, now the second one:
(a - b)^2
Let's just expand this:
(a - b)^2 = (a - b)*(a - b) = a*a + a*(-b) + (-b)*a + (-b)*(-b) = a^2 - 2ab - b^2

y is inversely proportional to x².
When x = 2, y = 8.
Find y in terms of x.
Answer: y=32/x^2
Step-by-step explanation: Please mark brainilest. Since y and x^2 are inversely proportional, x^2(y)=k. K is some constant. Since they gave us an example of x and y, we can calculate k as 4*8=32. So our updated equation is y(x^2)=32. Dividing both sides by x^2 we get y=32/x^2, so we have y in terms of x
Answer:
y = 32x
Step-by-step explanation:
y = k/x^2
8 = k/2^2
8 = k/4
8×4 = 32
k = 32

Angela’s bedroom has an area of (2x2-7x-15) square feet. The length of the room is (2x+3) feet. What is the width of her bedroom?
The width of her bedroom is x - 5
How to determine the widthIt is important to note that the formula for area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the roomw is the width of the roomNow, let's substitute the values into the formula, we have;
2x²-7x-15 = (2x+3)w
Divide both sides by the coefficient of w
w = 2x²-7x-15/(2x+3)
Factorize the numerator
w = 2x²- 10x + 3x - 15/(2x+3)
Factor the common terms of the numerator
w = 2x(x - 10) + 3(x - 5)/(2x+3)
enclose the expressions
w = (2x + 3)(x-5)/(2x+3)
Divide the common terms
w = x - 5 feet

Tim buys a new computer for $1200. After four years, he sells the computer to a friend for $450.
Let y represent the current value of the computer, and x represent the number of years. Write a
linear equation in slope-intercept form to model the value of the computer over time. Find the value
of the computer after 6 years.
A linear equation in slope-intercept form for computer; y = -187.5(x) + 1200.
The value of the computer after 6 years will be $75.
What is defined as the slope-intercept form?An intercept is a y-axis point whereby the slope of a line passes. It is the y-coordinate of a point on the y-axis at which a straight line or a curve intersects. This is represented by the equation for a straight line, y = mx+c, where m is the slope and c is really the y-intercept.Tim spends $1200 on a new computer.
He sells this same computer to that of a friend for $450 after four years.
Let y represent the computer's current value and x depict the number of years.
Create a linear equation in slope-intercept pattern to model the computer's value over time.
y = mx + b
y = 1200,
when x (time) is 0, thus b = 1200
when x = 4, y = 450,
Calculate the slope m.
4m + 1200 = 450
4m = 450 - 1200
m = -750/4
m = -187.5
Put the value of m in linear equation;
y = -187.5x + 1200
Noe, the value of computer after 6 years, put x = 6.
y = -187.5(6) + 1200
y = 75
Thus, the value of the computer after 6 years will be $75.

A light-year, sometimes spelt light year, is a huge measure of length used in astronomy that is comparable to approximately 9.46 trillion kilometers (9.461012 kph) or 5.88 trillion miles (5.881012 mi). A light-year, as defined by the International Astronomical Union (IAU), is the distance that light travels in a vacuum in one Julian year (365.25 days). The phrase light-year is frequently misconstrued as a unit of time since it contains the time-measurement word "year." The light-year is most commonly used in non-specialist contexts and popular scientific publications to indicate distances to stars and other cosmic distances.

Rachel is making premade 3-inch by 5-inch tile rectangles for her driveway. If it takes her 6 minutes to position each rectangle, how many hours will it take her to create a 2-foot by 4-foot pattern drive? Write your answer as a decimal. (ASAP)
The time taken to create the driveway is 7 hours 42 minutes
The dimensions of the rectangle tile = 3 inch by 5 inches
The area of the rectangle tile = Length × width
= 3×5
= 15 square inches
Time taken to position each rectangle = 6 minutes
The dimensions of the driveway = 2 foot by 4 foot
Convert the dimensions to inches
2 foot by 4 foot = 2×12 inches by 4×12 inches
= 24 inches by 48 inches
The area = Length × Width
= 24×48
= 1152 square inches
Number of tiles needed = Area of the driveway/ Area of the tile
= 1152/15
= 76.8
≈77 tiles
Time taken to create the drive way = Number of tile× Time taken to position each rectangle
= 77×6
= 462 minutes
= 7 hours 42 minutes
Hence, the time taken to create the driveway is 7 hours 42 minutes.

For the given data set, median is better choice for measure than mean because:
Median is usually a better measure of the center when there are extreme values as it is remains unaffected by the precise numerical value. The most common measure of the center is mean.
What is median and mean?Adding all numbers in the data and dividing it by the number of values in the set gives mean of a data. Whereas, median is the middle value in a data set, implying that 50% of data points can have a value smaller or equal to the median and 50% of data points can have a value higher or equal to the median.
For a small data set, firstly, count the number of data points and arrange them in increasing order. If the number of data is odd, then add 1 to the number and divide the result by 2 to obtain the rank of the data whose value is the median.

Proved that ∠ 2 = 107° because these two angles are supplementary angles .
What are supplementary angles ?Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. If the two additional angles are combined, they create a straight line and an angle.
However, it should be emphasized that the two complementary angles do not necessarily need to be close to one another. As a result, any two angles can be supplementary if their sum is 180 degrees. However, it should be emphasized that the two complementary angles do not necessarily need to be close to one another. So, if two angles are complementary, they can be any two angles.
Given : ∠ 1 and ∠ 2 are supplementary angles
that is ∠ 1 + ∠2 = 180 °
