The area of a square is the square of the length of a side is a^2.
The quantity of space occupied within the square can be used to calculate the size of a square using mathematics. We'll go over the equation for calculating the square's area below. It is mainly known for its geometric quadrilaterals. The simplest definition of a square is a regular polygon with four equal sides. A square has all the same facts and characteristics as regular polygons.
The number of square units that are anticipated to fill a square is used to describe the area of a square. The area is typically defined as the area included by the confines of a level article or 2D figure.
Mathematical Area of Square Formula = a×a=a^2.

Line A passes through (0, -3) and (5, -1). Find the equation of Line A.
Answer:
[tex]y=\frac{2}{5}x-3[/tex]
or
[tex]y+3=\frac{2}{5} (x-0)[/tex]
Step-by-step explanation:
Finding the Equation of a Line Given Two Points:In order to find the equation of a line, we must identify point (x,y) and slope (m). Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Point-slope formula: [tex]y-y_1=m(x-x_1)[/tex]Slope-intercept formula: [tex]y=mx+b[/tex]We are given two points on Line A: (0,-3) and (5,-1). We can assign each integer to a variable in the slope formula (see above):
[tex]x_1=0[/tex]
[tex]y_1=-3[/tex]
[tex]x_2=5[/tex]
[tex]y_2=-1[/tex]
As we have identified point, we can now work to identify slope by substituting our points into the slope formula:
[tex]m=\frac{-1-(-3)}{5-0}=\frac{2}{5}[/tex]
Now that we have identified both point and slope for Line A, we can format these values in point-slope form. Substitute values into the formula:
[tex]y-(-3)=\frac{2}{5} (x-0)=y+3=\frac{2}{5}x[/tex]
Solve for [tex]y[/tex] to achieve an answer in slope-intercept form ([tex]y=mx+b)[/tex]:
[tex]y=\frac{2}{5} x-3[/tex]
Is the line through points (-3,2) and (4, -1) parallel to the line that contains the points (1,3) and (-2, -4)?
Are the two lines parallel?
How do you know?
Considering the expression of a line, they do not have the same value of m. So, the two lines are not parallel.
Linear equation o lineA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:
m= (y2 - y1)÷ (x2 - x1)
Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.
Parallel lineParallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.
Two lines are parallel if they have the same slope and different y-intercepts. That is, they have the same value of m and different value of b.
Lines in this caseIn this case, you can calculated the slope of the two lines as:
Being (x1,y1)= (-3,2) and (x2,y2)= (4, -1), the slope m can be calculated as:
m= (-1 -2)÷ (4 - (-3))
Solving:
m= (-3)÷ 7
m= -3/7
Being (x1,y1)= (1,3) and (x2,y2)= (-2,-4), the slope m can be calculated as:
m= (-4 -3)÷ (-2 -1)
Solving:
m= (-7)÷ (-3)
m= 7/3
You can observe that they do not have the same value of m. Finally, the two lines are not parallel.

Solve the following equation. x/6 + 4 = 20 Then place the correct number in the box provided.
Answer:
x = 96
Step-by-step explanation:
[tex]\frac{x}{6} +4=20[/tex]
1. Isolate the variable 'x'.
1a. Subtract 4 so the equation becomes [tex]\frac{x}{6} =16[/tex]
2a. Multiply both sides by 6 to turn the fraction into a normal number, which becomes x=96.
Answer:
[tex] \sf \large \: x=96[/tex]
Step-by-step explanation:
Let's solve your equation step-by-step.
x/6+4=20
Step 1: Simplify both sides of the equation.
1/6x+4=20
Step 2: Subtract 4 from both sides.
1/6x+4−4=20−4
1/6x=16
Step 3: Multiply both sides by 6.
6*(1/6x)=(6)*(16)
x=96
Lauren was trying to approximate the solution to n² = 115. She said that it lies
between √100 and √121. Therefore, it lies between 4 and 5, however a little closer
to 5. She approximated it to be about 4.7. Do you agree or disagree with her
reasoning? Explain.
What she approximated as 4.7 is not correct because the nearest perfect squares are 10 and 11 which are different from what she got.
How to find the square root of a number?We are told that Lauren is trying to approximate the solution to n² = 115.
Now, she has figured out that it lies between √100 and √121..
Now, √100 = 10 and √121 = 11. Thus, we can say that if she says it is between 4 and 5, then she is wrong because the nearest perfect squares are 10 and 11 which are different from what she got.

Then 2% of x will be;
x + 2%of x = 37,740
x + 2x/100 = 37,740
x + 0.02x = 37,740
1.02x = 37,740
x = 37,740/1.02
x = 33500

The value of the greatest integer is equal to 1.
We are given that:
The sum of an integer and 7 times the next consecutive odd integer is 6
Consecutive numbers are the numbers that follow each other continuously in the order from smallest to largest. For example 34 and 35.
Let the first number be x.
Second number = x + 2 ( as we need an odd integer)

The bucket and the jar together will hold (c + d) litres of water.
What is defined as linear equation on two variables?A linear function does have a positive relationship, so increasing one variable (input variable) causes a rise in the second variable (output variable), implying that the variables have always been directly proportional. As a result, the graph of such a linear function is a straight line with a constant slope.Correspondingly, a linear equation is a first-order algebraic equation with two variables and terms with exponents of one.A linear equation in 2 variables [x and y] is any equation with the form:
ax + by = c and at least one of a or b being non-zero.
This is known as the equation's General Form.
For the given question;
The water hold by bucket = c litres.
The water hold by jar = d litres.
Thus, the water hold by both bucket and jar is is linear equation with two variable c and d.

find the measure of the indicated angle that makes lines u and v parallel
To make lines u and v parallel, the indicated angle must be 108°.
What are angles?An angle is a figure in Plane Geometry formed by two rays or lines that share a common endpoint. "Angle" comes from the Latin word "angulus," which means "corner." The two rays are referred to as the sides of an angle, and the common endpoint is referred to as the vertex.So, if two parallel lines n and m intersect, then all the angles generated in line m must be exactly the same as the angles generated in line n.
At the intersection of two lines, two adjacent angles must add up to 180°.According to the first criterion, the missing angle denoted by a "?" must have the same measure as the angle just below the 72° angle.According to the second (and previously used) criterion, we must have:
? + 72° = 180°When we solve that, we get:
? = 180° - 72° = 108°Therefore, to make lines u and v parallel, the indicated angle must be 108°.
