Arrays are useful representations of multiplication concepts of the commutative property.
We need to find how can you use an array to show the commutative property.
The word 'commutative' originates from the word 'commute', which means to move around. Hence, the commutative property deals with moving the numbers around. So mathematically, if changing the order of the operands does not change the result of the arithmetic operation then that particular arithmetic operation is commutative.
An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplicationconcepts (among other ideas in mathematics).
The commutative property of multiplication can be neatly illustrated using an array. For example, the array above could be read as 2 rows of 6, or as 6 columns of 2. Or the array could be physically turned around to show that 2 rows of 6 have the same number as 6 rows of 2.
Therefore, arrays are useful representations of multiplication concepts of the commutative property.

The product 1374 x 6 is 8244.
Given,
1374 x 6
We need to find the product.
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = 30
6 x 6 = 36
6 x 7 = 42
6 x 8 = 48
6 x 9 = 54
6 x 10 = 60
Find the product of 1374 x 6.
We have,
1374 x 6
= (6x1)(6x3)(6x7)(6x4)
= 6(18)(42)(24)
Add the left digit 2 from 24 to 42 and keep 4 from 24
= 6(18)(42+2)4
= 6(18)(44)4
Add 4 from 44 to 18 and keep 4.
= 6(18+4)44
= 6(22)44
Add 2 from 22 to 6 and keep 2 from 22.
= (6+2)244
= 8244
Thus the product of 1374 x 6 is 8244.

Answer:
First piece = 4 inch, second piece = 12 inch , third piece = 20 inch
Step-by-step explanation:
Length of the board = 36 inch
Let, the length of the first piece = X
So, according to the question
Second piece = 3 times X = 3x
Third piece = 5 times X = 5X
Now, first piece + second piece + third piece = total length of the board
⇒ X + 3X+ 5X = 36 inch
or, 9X = 36 inch
or, X = 36/9 = 4 inch
So, length of the : First piece = 4 inch
Second Piece = 3X = 3 x 4 = 12 inch
Third piece = 5X = 5 x 4 = 20 inch
answer 16.99%
We are given this function:
8700 is the initial amount.
1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.
1.04 * 100% = 104%
Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.
In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.
104% - 100% = 4%
This would be our solution if we don't have an exponent.
We have exponent so first step is to calculate the number and then we repeat the steps from above.
1,16985856 * 100% ≈ 116,99%
116.99% - 100% = 16.99%
So, final solution is growth of 16.99%

Answer:
single solution : (4 ; 6)
Step-by-step explanation:
hello :
4x-y=10.....(1)
y=2x-2.....(2)
put the value for y in (1) :
4x-(2x-2)=10
4x-2x +2 = 10
2x=8
x=8/2 =4
but : y = 2x-2
so : y =2(4)-2=6
single solution : (4 ; 6)
