A rectangle has four sides and angles at 90 degree.
What is a rectangle?A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
Given: shape of a rectangle
A rectangle is closed flat shape, having four sides, and each angle equal to 90 degrees. The opposite sides of the rectangle are equal and parallel.
Hence, A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°).

What is the solution to the equation 6y –2(y + 1) = 3(y – 2) 6? a. y = –10 b. y = –2 c. y = 2 d. y = 6
The solution to the equation 6y - 2(y + 1) = 3(y - 2) 6 is y = -34. So, the correct answer to the question is a. y = -10.
What is algebraic equation ?
An algebraic equation is a mathematical statement that asserts the equality of two expressions, each of which is made up of numbers and/or variables. The expressions are separated by an equal sign (=). The goal of solving an algebraic equation is to find the value(s) of the variable(s) that make the equation a true statement.
To find the solution to the equation 6y - 2(y + 1) = 3(y - 2) 6, we must first simplify both sides of the equation by following the order of operations (PEMDAS). First, we simplify the right side of the equation: 3(y - 2) 6 = 3y - 6 * 6 = 3y - 36. Next, we simplify the left side of the equation: 6y - 2(y + 1) = 6y - 2y - 2 = 4y - 2.
Now we have the equation: 4y - 2 = 3y - 36
Next, we can add 2 to both sides of the equation and get: 4y = 3y - 34
Finally we subtract 3y from both sides of the equation and get: y = -34
Therefore, the solution to the equation 6y - 2(y + 1) = 3(y - 2) 6 is y = -34. So, the correct answer to the question is a. y = -10.

The function f(x) is f(x) = -2/3 x -8. The function g(x) is g(x) = -1/6 x - 2
What is a function?
A function from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.
Given that f(x) is a linear function. The value of f are f(-9) = -2 and f(-3) = -6.
Assume that, f(x) = ax + b
Now putting x = -9 in f(x) = ax + b:
f(-9) = a(-9) + b
Putting f(-9) = -2
-2 = -9a + b ....(i)
Now putting x = -3 in f(x) = ax + b:
f(-3) = a(-3) + b
Putting f(-3) = -6
-6 = -3a + b .....(ii)
By using the elimination method solve equation (i) and (ii).
Subtract equation (ii) from equation (i)
-9a + b = -2
-3b + b = -6
(+) (-) (+)
__________
-6a = 4
Divide both sides by -6:
a = -4/6
a = -2/3
Putting a = -2/3 in equation (i)
-6 = -3(-2/3) + b
-6 = 2 + b
b = -6 - 2
b = -8
Therefore, f(x) = -2/3 x -8
Now compare f(x) = -2/3 x -8 with f(x) = ax + b
a = -2/3 , b = -8
The y-intercept of f(x) is b = -8
The x-intercept of f(x) is b/a = -8/(-2/3) = 12
The y-intercept of g(x) is 6 more than f(x). Thus the y-intercepts of g(x) is 6 + (-8) = -2
The x-intercept of g(x) is 12.
Assume that the linear equation of g(x) is g(x) = hx + k
The y-intercept of g(x) is k = -2
The x-intercept of g(x) is k/h = 12
Putting k = -2:
-2/h = 12
h = -2/12
h = - 1/6
The linear equation of g(x) is g(x) = -1/6 x - 2

Bryson , it has 12 cards each card is a different number from 1 to 12 he chooses a card at random. how likely is it for Bryson to choose an odd number?
Answer:
as likely as not
Step-by-step explanation:
if there are 12 cards then 6 would have even and and 6 would be odd so it is a 50/50 chance so it just as likely as it isn't
The event has an “equal chance” to happen or not, the probability will be 1/2. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, Bryson has 12 cards each card is a different number from 1 to 12.
Here, total number of outcomes = 12
Number of favorable outcomes = 6 (odd number of cards)
Now, probability of an event = 6/12
= 0.5
If the event has an “equal chance” to happen or not, the probability will be 1/2.

3. The slope of Lin graph (m= 30) is less than Correct graph (m=40).
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

m = Δy/Δx where, m is the slope
Given:
1. Lin started with reading 30 pages.
Then, after 1sr day she will read the 40 pages per day.
So, if number of days represented by x- coordinates and number pages pages by y- coordinate we get
On first day (0. 30)
On second day (1, 30+40)= 91. 70)
On third day (2, 70+40)= (2, 110)
On fourth day (3, 110+40) = (3, 150)
and, On fifth day (4, 150+40)= (4, 190)
Hence, Line made mistake as after 4 days he completed 190 pages.

What is the gradient of the line y 6x =- 5?
After solving, the gradient of the line y = 6x - 5 is 6.
We have to find the gradient of the line y = 6x - 5.
The formula known as the slope relates to the method for calculating a line's steepness and inclination. The x and y coordinates of the locations along the line can be used to determine the slope of the lines. It is the ratio of the change in the y-axis to the change in the x-axis, to put it another way.
By utilizing the line equation, the slope of any line may be expressed as
y = mx + b, where m = gradient.

What is the absolute value?
Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.
The absolute value of a real number, denoted by |a|, is the non-negative value of a without regard to its sign.
Therefore, if a is greater than or equal to zero, the absolute value of a is equal to itself.
On the other hand, -a is the negative of a, which is only the case when a is less than zero.

What is the absolute value?Without taking direction into account, absolute value describes how far away from zero a certain number is on the number line. A number can never have a negative absolute value. The non-negative value of a, indicated by the symbol |a|, is the absolute value of a real number, regardless of its sign. It follows that if an is higher than or equal to zero, its absolute value is also zero.
However, -a is the opposite of a, and is only true when an is less than zero. This means that when an is greater than 0, |a| can never equal -a because the absolute value is always non-negative whereas -a is always negative.

How can you break apart the factor 4 into equal addends to find the factor 4x7
We can add the factor 4 seven times to find the product 4 × 7.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number. a × b means that a is added to itself b times or b is added to itself a times.
So we know that multiplication is basically addition of one of the numbers up to the times as that of the other number.
Given, we have to find the product of 4 × 7, in terms of addition, by using the factor 4.
The meaning of the product of 4 and 7 is that 4 is adding to itself 7 times or 7 is adding to itself 4 times.
Since we need to break the product in terms of 4 as addends, we can write,
4 × 7 = 4 + 4 + 4 + 4 + 4 + 4 +4
