Fast please!! I need it

Step-by-step explanation:

this is the answer ok

hope it helps you.

Multiply 3 and 6 to get 18.

Multiply 1 and 3 to get 3.

Add 3 and 1 to get 4.

The least common multiple of 6 and 3 is 6. Convert 23/6 and 4/3 to fractions with denominator 6.

Because 23/6 and 8/6 have the same denominator, subtract them by subtracting their numerators.

Subtract 8 from 23 to get 15.

Reduce the fraction 15/6 to its lowest terms by extracting and cancelling out 3.

5/2 as a mixed fraction will become :-

The width of the rectangle will be 16 unit.

Explanation: Since, Given- 192 square unit is the area of the rectangle.

but again, according to the the area is represent by the expression

Then, Steps will be- Step 1:

Step2:x(x+4) = 192, where x is the length of the rectangle. And the width is x+4.

Step3:  

Step4: (x+16)(x-12)=0

Because the lenght can not be negative, the lenght is 12 and width is 16.

so, option 4th will be right.
