Equivalent expressio

When two expressions can be reduced to a single third expression or when one of the expressions can be written in the same way as the other, they are said to be equivalent. When values are replaced for the variable and both expressions yield the same result, you may also tell if two expressions are equal.

Because both expressions have the same value for any value of x, 3(x + 2) and 3x + 6 are identical expressions. 3x + 6 = 3 × 4 + 6 = 18. Algebraic equations with equivalent solutions or roots are called equivalent equations.

An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. Expressions that are equivalent do the same thing even when they have distinct appearances. In the event when two algebraic expressions.

Answer:

The third side of the triangle must be greater than 4 and less than 19. This follows from the Triangle Inequality Theorem, which states that the sum of any two sides of a triangle must be greater than the third side, and the difference between any two sides of a triangle must be less than the third side. Therefore, the third side must be greater than 4 (5 + 4) and less than 19 (14 - 4).

The area of a triangle can be calculated using the formula A=1/2*b*h, where b is the base of the triangle and h is the height.

The area of a triangle can be found by using the formula A = 1/2bh, where b is the base of the triangle and h is the height of the triangle. To find the area of a triangle in square units, you would need to multiply the base and the height of the triangle and then divide the result by 2.Once you have these two measurements, simply plug them into the formula and calculate the area.

To calculate the area, we need to first measure the base and the height. Once we have the measurements, we can calculate the area by multiplying the base by the height and then dividing by two. For example, if the base is 8 units and the height is 6 units, the area of the triangle will be 24 square units (A = 1/2*8*6 = 24).

The Factor Theorem states that if a polynomial is divided by (x-a) then the remainder is equal to zero if and only if (x-a) is a factor of the polynomial.

To solve the Factor Theorem, first you need to determine the polynomial and the value of (x-a).

Then you divide the polynomial by (x-a). To do this, use synthetic division. Synthetic division is a shorthand way of dividing a polynomial by a linear factor.

If the remainder is 0, then the polynomial is divisible by (x-a). If the remainder is not 0, then (x-a) is not a factor of the polynomial.

To summarize, the Factor Theorem states that if the remainder is 0 after dividing a polynomial by (x-a), then (x-a) is a factor of the polynomial.  The Factor Theorem can be solved by using synthetic division.

The first step in solving an inequality is to isolate the variable on one side of the inequality sign. This is also known as "clearing the inequality" of the variable. This can be done by using inverse operations such as addition, subtraction, multiplication, and division.

For example, if the inequality is 3x + 2 > 7, the first step is to isolate the variable x by subtracting 2 from both sides:

3x + 2 > 7

3x > 5

Then, divide both sides by 3 to get x > 5/3

This is the first step in solving an inequality, as now the variable x is isolated on one side of the inequality sign, and it's clear what the inequality is asking for.

It's important to note that when solving inequalities, it's crucial to keep the direction of the inequality sign the same, meaning if you multiply or divide by a negative number, you need to switch the direction of the inequality sign as well.

Also, it's important to check if the inequality is not valid, if the operation you are doing creates a division by zero, it will be an invalid inequality.

The shorter side of the triangle will be opposite to 30° angle and larger side will be opposite to 90° angle .

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

The side opposite the smallest angle is the one that is the shortest. The shortest side is opposite the angle that you already know to be the shortest.

The side opposite the right angle is always the hypotenuse of a right triangle. In a right triangle, it is the longest side.

If the rectangular area has maximum area, the dimension of the rectangular area is 62.5 m×62.5 m. The area is 3,906.25 square meters.

To enclose a rectangular area with one side bordered by a stream, Farmer Mei can use the remaining 250 meters of fence to form the other three sides of the rectangle. Since the rectangle has two sides of equal length (the width and the height), we can set up the equation:

2L + 2W = 250

where L represents the length of the rectangle and W represents the width.

Solving for one variable in terms of the other:

W = 250/2 - L

The area of the rectangle is given by the formula:

A = L×W

Now, we can substitute the value of W from the above equation into this one to get:

A = L × (250/2 - L)

A = 125L - L²

To find the maximum area, we need to take the derivative of A with respect to L and set it equal to 0.

dA/dL = 250/2 - 2L = 0

Which gives us the value of L = 125/2 = 62.5m

Now, we can substitute this value of L back into the equation for W to find the width of the rectangle:

W = 250/2 - 62.5 = 62.5m

Therefore the dimensions of the rectangle is 62.5m x 62.5m and the maximum area that can be enclosed is 62.5m x 62.5m = 3,906.25 sq m.
