What is a square? What is a mathematical equation? What do you mean by domain and range of a function?In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle with two equal-length adjacent sides.
Area: (side)²Perimeter: 4 x sideNumber of vertices: 4Number of edges: 4Internal angle: 90°Properties: Convex polygon, Equilateral polygon, Isogonal figure, Isotoxal figure, CyclicType: Quadrilateral, Regular polygonA mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
A mathematical equation is used to equate two expressions.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is square ABCD and AB = 2x + 4 and CD = 3x - 5
Now -
AB = CD
Equation will be -
2x + 4 = 3x - 5
4 + 5 = 3x - 2x
x = 9
and
AB = BC = CD = AD = 2x + 4 = 2 x 9 + 4 = 22
BC = 22
Therefore, the equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

Answers
Answer:
a) 13%
b) 45%
c) 16%
Step-by-step explanation:
To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31, therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.

O a square with side length 4 inches
O a 2 inch by 8 inch rectangle
O a circle with radius 2 inches
O a right triangle with legs 4 inches long
O a heart-shaped base with an area of 16 square inches
Answers
Answer: a square with side length 4 inches
a 2 inch by 8 inch rectangle
a heart-shaped base with an area of 16 square inches
Step-by-step explanation: The given height is 5. Any base with an area of 16 square inches will be an acceptable base.
For example, if the circular base had a radius of about 2.257 inches, its area would be 16 square inches
(2.257)² ≈ 5.093
5.093 × 3.1416 ≈ 16
16 × 5 = 80
The base for this prism should be like
a square with side length 4 inches.
a 2 inch by 8 inch rectangle.
a heart-shaped base with an area of 16 square inches.
Could be the base for the prism:Since
The given height is 5.
Any base with an area of 16 square inches should be considered as an acceptable base.
Like if the circular base had a radius of about 2.257 inches, its area would be 16 square inches
So, it be like
(2.257)² ≈ 5.093
Now
5.093 ( 3.1416) ≈ 16
16 ( 5) = 80

The value of the angle,x=50.531°. The angle is obtained by the sin law.
What is the triangle?A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
From the sin rule;
[tex]\rm \frac{AB}{sin \angle ACB} =\frac{BC}{sin \angle BAC} \\\\ \rm \frac{5.6}{sin \angle ACB} =\frac{9.3}{sin \angle 50^0} \\\\ \angle ACB=27.49^0[/tex]
For the same angles;
[tex]\rm \angle ACB=\angle BCD[/tex]
From the exterior angle theorm ;
[tex]\rm \angle BCD+\angle CBD= \angle ADB[/tex]
∠CBD=x
∠ABD=78°
Putting the obtained values;
27.469°+x=78°
x=78°-27.469°
x=50.531°
Hence,the value of the angle,x=50.531°.

simplify 1/2 (4x+2) - (-2x)
Answers
Answer:
4x + 1 is the simplified expression
Step-by-step explanation:
We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.
The first step involves mulitplication and distribution property:
1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)
2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).
Bow the expression is almost simplified as it is:
2x + 1 -(-2x)
The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:
3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.
4) Now we know that -(-2x) is the same as: + 2x.
5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.

What is the approximate average rate of change for f(x) = 20(0.5) from
x = 2 to x = 2?
Answers
Answer:
It is: (f(2) - f(0))/(2 - 0)
f(2) = 250(0.5)(2) = 250
f(0) = 250 (0.5)(0) = 0
So: (250 - 0)/(2 - 0) = 250/2 = 175
The average rate of change is 175.

Mom buys a rectangular rug with an area of LaTeX: 7\frac{1}{6}7 1 6 square meters. The length of the rug is LaTeX: 3\frac{1}{3}3 1 3 meters. What is the width of the rug?
Answers
Answer:
2 3/20 metres
Step-by-step explanation:
Area of the rug = Length × width
Given
Area = 7 1/6 metres = 43/6 m
Length = 3 1/3 metres = 10/3 m
Required
Width
From the formula
A = LW
W = A/L
Substitute the given values
W = 43/6÷10/3
W = 43/6×3/10
W = 43/2 ×1/10
W = 43/20
W = 2 3/20 m
Hence the width of the rug is 2 3/20 metres
