What is rectangle?
" A rectangle is a two dimensional shape whose opposite sides are parallel and congruent to each other. Each of the interior angle is of measure 90°."
What is square?" A square is a parallelogram whose all sides are congruent to each other. Each of the interior angle is of measure 90°."
Formula used
Area of rectangle = length × width
Area of square = (side)²
According to the question,
length of a rectangle = 12x
width of a rectangle = 3x

what is the slope line
Answer:
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Nita finds that the expression (a + 1) 2 is sometimes, but
not always, greater in value than (a + 1) 3 when she evaluates both expressions
for the same value of a. How do you explain this finding?
I guess the expressions are supposed to be (a + 1)² and (a + 1)³.
Consider the inequality,
(a + 1)² > (a + 1)³
Move everything to one side:
(a + 1)² - (a + 1)³ > 0
Factorize the left side:
(a + 1)² (1 - (a + 1)) > 0
-a (a + 1)² > 0
a (a + 1)² < 0
Notice that the left side is exactly 0 if either a = 0 or a = -1.
Now consider the following 3 cases:
• If a < -1, then a is negative, while (a + 1)² is always non-negative, which means a (a + 1)² will always be negative.
• If -1 < a < 0, then again a is negative, so a (a + 1)² is also negative.
• If a > 0, then a (a + 1)² is always positive.
So the inequality is satisfied for all a in the interval (-∞, -1) ∪ (-1, 0). This is to say that (a + 1)² is always greater than (a + 1)³ if a is chosen from this domain.
Another way to look at this: assume a + 1 falls between -1 and 1. Whenever you scale a number between -1 and 1 by another number in the same range, the product will always be smaller than the original number.
More concretely, let's say a + 1 = 1/2. So for instance, 1/2 * 1/2 = (1/2)² = 1/4, and 1/4 is clearly smaller than 1/2. If we multipy again by 1/2, we get 1/2 * 1/2 * 1/2 = (1/2)³ = 1/8, which is smaller than 1/4.

question: Find the values of k and b if it is known that the graph of y=kx+b goes through points (2, 10) and (−7, −10).
what is k and what is b
PLEASEEEEE
Answer:
k = 20/9
b = 50/9
Step-by-step explanation:
slope intercept form: y = mx + b
given equation: y = kx + b
(-10-10)/(-7-2)
= 20/9
10= 2 x 20/9 + b
90 = 40 + b
b = 50
y = 20x/9 + 50

A car travels along a straight road 100 m east then 50 m west. Find distance and displacement of the car.
Given parameters:
First move = 100m east
Second move = 50m west
Unknown:
Distance = ?
Displacement = ?
Solution:
Distance is total path length covered
Displacement is the distance in a specific direction from start to finish.
-----------------------→
100m
←---------
50m
So,
Distance = first move + second move = 100 + 50 = 150m
Displacement = 100 - 50 = 50m due West

It has generally been believed that it is not feasible for men and women to be just friends (The New York Times, April 12, 2012). Others argue that this belief may not be true anymore since gone are the days when men worked and women stayed at home and the only way they could get together was for romance. In a recent survey, 186 heterosexual college students were asked if it was feasible for men and women to be just friends. Thirty-two percent of females and 57% of males reported that it was not feasible for men and women to be just friends. Suppose the study consisted of 100 female and 86 male students.
a. Construct a contingency table that shows frequencies for the qualitative variables Gender (men or women) and Feasible (yes or no).
b. Find the probability that a student believes that men and women can be friends.

what does it mean to say that a number is a perfect square
Answer:
A perfect square is the product of a rational number multiplied by itself.
4, 9, and 16 are perfect squares
1, 2, 3, 5, 6, etc. are not perfect squares
Step-by-step explanation:
Answer:
please mark brainliest!
Step-by-step explanation:
NON-DETAILEDA number that is a perfect square is a number that can be square rooted kind of in a perfect match. Example would be 9 because it can be square rooted by 3 for 3 * 3. Another example that would not be a perfect square would be 30 because it can divided by 6 * 5 but neither one of those numbers are perfect squares.
DETAILEDA number called a perfect square means that the number has an exact squared root. In other words, the number has an squared power, which is exact.
Other way to see this, it's taking natural number 1, 2, 3, 4 then, applying the squared power to each one, the results of each squared power is what we call a perfect square. For example, 1, 4, 9, 16, 25, 36, are all perfect square, because they are the result of a squared power:
[tex]1^{2} = 1\\2^2 = 4\\3^2 = 9\\4^2 = 16\\5^2 = 25\\6^2 = 36[/tex]
Solve for x.
16 = -2x - 1
x=-7 1/2
x=-8 1/2
x=8 1/2
x=7 1/2
Answer:
x= -8 1/2

Find the x - and y-intercepts of the graph of the linear equation 2x + 3y = 12.
The x-intercept is
The y-intercept is
Answer:
Y intercept = (0,4)
X intercept = (6,0)
Step-by-step explanation:
First you need to make the equation slope intercept form.2x+3y=12
To do so, you need to get y on it's own (or on one side)
Subtract 3y from the left side.-3y+12=2x
Then, divide everything out by -3y-4=-2/3x
Add four to the other sidey= -2/3x +4
-2/3x= slope while 4= y intercept
You can also graph it on desmos and find the y intercept and x intercept
We want to find the x and y-intercepts of a given equation.
The solution is:
The x-intercept is x = 6 The y-intercept is y = 4First, we start by defining what x-intercept and y-intercept are.
The x-intercept is the x-value at which the graph of the equation intercepts the x-axis, and is equivalent for the y-intercept.
So, for a given function y = f(x).
We define the y-intercept as the value of y when we define x = 0.
And we define the x-intercept as the value (or values) of x when y = 0.
Here we have:
2x + 3y = 12
So to get the x-intercept, we just need to define y = 0 and solve for x.
2x + 3*0 = 12
2x = 12
x = 12/2 = 6
To get the y-intercept, we just need to define x = 0 and solve for y.
2*0 + 3*y = 12
3*y = 12
y = 12/3 = 4
Then we can conclude:
The x-intercept is x = 6 The y-intercept is y = 4If you want to learn more, you can read:

hope this helped, if you need a more in depth answer to how i did it just ask
Answer:
Hello! I hope I’m correct! :)
Step-by-step explanation:
The answer should be V = 10
First, Add 10 to both sides.
-6(2v-8) = -82+10
Next, Simplify
-6(2v-8) = -72
Than, divide both sides by -6
= -72/-6
{Note: two negatives makes a positive}
= 72/6
Simplify.
2v-8=12
Add (+) 8 to both of the sides.
2v= 12+8
Simplify 12+8 to...
2v = 20
Now, divide both sides by 2
V = 20/2
Since we have 20/2, we need to simplify (divide 20 & 2)
20 divided by 2 = 10
V = 10
Therefore the answer is v = 10Hope this helps! If you have any questions about these steps, feel free to ask! Have a nice day! :)

What’s 4.5 rounded to the nearest whole number
Answer: 5
Step-by-step explanation:
When the number after the point is 5 and above round up
4.5 rounded to the nearest whole number is 5.
When you round a decimal number to the nearest whole number, you are determining which whole number it is closest to.
For 4.5, you can visualize it on the number line.
The decimal number 4.5 lies exactly midway between 4 and 5.
To round to the nearest whole number, we look at the digit immediately to the right of the decimal point, which is 5.
Since 5 is greater than or equal to 5 (the midpoint), we round up to the next whole number, which is 5.
Therefore, 4.5 rounded to the nearest whole number is 5.
