6 = a/4 + 2

What’s the answer for the variable a?

a = 16

Step-by-step explanation:

6 = a/4 + 2

4 = a/4            Subtract 2 from both sides

16 = a                 Multiply 4 to both sides

P = 6 + 4w

Step-by-step explanation:

The length of a rectangle is 3 times greater than its width

Therefore the perimeter of a rectangle can be calculated as follows

P= 2L + 2w

P = 2(w + 3) + 2w

P= 2w + 6 + 2w

P= 6 + 4w

Hence the expression which gives the perimeter of the rectangle in terms of its width is P = 6 + 4w
