The associative property states that when adding or multiplying three or more terms, you can group the terms in any order and still get the same answer. The expression must use only one operation. For example, 4 × 3 × 2 can be thought of as 4·(3 · 2), which is 4 · 6, or as (4 · 3) · 2, which is 12 · 2.
The associative property works with addition and multiplication, but not division and subtraction.
The associative property works with addition and multiplication, but not division and subtraction because the grouping of terms affects the result of the operation.
A mathematical concept known as the associative property governs the addition and multiplication of three or more terms. It claims that the way the phrases are grouped has no bearing on how the operation turns out.
This implies that the same result may be obtained by adding or multiplying three or more terms in any sequence. Nevertheless, division and subtraction are not covered by the associative property.
We should take a gander at the accompanying cases to show how expansion and increase are connected:
Example 1: Addition
(2 + 3) + 4 = 2 + (3 + 4)
5 + 4 = 2 + 7
9 = 9
Example 2: Multiplication
(2 × 3) × 4 = 2 × (3 × 4)
6 × 4 = 2 × 12
24 = 24
We can observe from both cases that the word grouping has no impact on the operation's outcome. The associative characteristic, therefore, applies to both addition and multiplication.
The associative characteristic, however, does not apply to division and subtraction. For instance:
(8 ÷ 4) ÷ 2 ≠ 8 ÷ (4 ÷ 2)
2 ÷ 2 ≠ 8 ÷ 2
1 ≠ 4
We can observe from this example that the term grouping has an impact on the operation's outcome. The associative property does not, therefore, apply to division.
The associative property does not also hold for subtraction. For instance:
(8 - 4) - 2 ≠ 8 - (4 - 2)
4 - 2 ≠ 8 - 2
2 ≠ 6
In this example, we can again see that the grouping of terms affects the result of the operation. Therefore, the associative property does not apply to subtraction.

What is the angle bisector theorem?
The angle bisector theorem states that a triangle's angle divides the opposing side into two portions that are proportionate to one another.
We have given,
Triangle, Let's consider it ΔABC,
then,
Measures of Angles ∠B= 37, ∠C=32, and side AD = 82
To find x =?
In the triangle side AD is the bisector, it forms a new triangle ΔADC.
According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.
As per the Angle bisector theorem, the ratio of the line segment BD to DC equals the ratio of the length of the side AB to AC.
To find AB & AC:
sin θ = side opposite to angle θ / hypotenuse
cos θ = side adjacent to angle θ / hypotenuse
sin θ = AD / AB
sin 37 = 82 / AB
AB = 82/ sin 37
AB = 136.25
cos θ = BD / AB
cos θ = BD/136.25
BD = cos37 * 136.25
BD = 104.9
sin θ = AD / AC
sin32 = 82 / AC
AC = 149
cos32 = DC / AC
cos32 = DC / 149
DC = 123.67
So, x = BD + DC
x = 104.9 + 123.67
x = 228.57
Hence, the value of the x is 228.57 units.

find the value of y in the proportion (4y+5):3=(y+7):4
The value of y in the given proportion is 1/13.
In mathematics, a proportion is a statement that two ratios are equal. A ratio is a comparison of two quantities, typically written as a fraction. For example, if we have two quantities, a and b, then the ratio of a to b is written as a/b.
A proportion is written in the form a/b = c/d, where a, b, c, and d are numbers. This means that the ratio of a to b is equal to the ratio of c to d. We can also write this as a:b = c:d.
To solve the proportion:
(4y+5):3=(y+7):4
We can cross-multiply and simplify:
4(4y+5) = 3(y+7)
16y + 20 = 3y + 21
Subtracting 3y from both sides:
3y + 20 = 21
Subtracting 20 from both sides:
13y = 1
Dividing both sides by 13:
y = 1/13
Therefore, the value of y that satisfies the proportion is y = 1/13.
