Question
Write both equations for the array.
- 3 + 3 + 3 + 3 = 12, 4 + 4 + 4 = 12
- 2 + 2 + 2 + 2 = 8, 4 + 4 + 4 = 12
- 3 + 3 = 6, 4 + 4 = 8
- 3 + 3 + 3 + 3 + 3 = 15, 4 + 4 + 4 = 12
Hint:
Numbers are the symbols used for counting or measuring these are the basics of mathematics. These counting numbers start with one and continues till infinity or endless. Here, we have to find the equation of the array in the above question by using these counting numbers in row- wise and column- wise.
The correct answer is: 3 + 3 + 3 + 3 = 12, 4 + 4 + 4 = 12
In the question an array is given using which we have to find both the equations.
According to the given array,
Number of cars in first row=3
Number of cars in second row=3
Number of cars in third row=3
Number of cars in fourth row=3
Here, the equation of the given array row- wise will be 3+3+3+3=12.
Number of cars in first column= 4
Number of cars in second column=4
Number of cars in third column=4
Here, the equation will be 4+4+4=12.
So, both the equations of the given array are 3+3+3+3=12 and 4+4+4=12.
Therefore the correct option is a, i.e., 3+3+3+3=12, 4+4+4=12.
