The area of a rectangular fountain is x2 + 9x + 20 square feet. A 5-foot walkway is built around the fountain. Find the dimensions of the outside border of the walkway. The dimensions of the outside border of the walkway are _ feet and _ feet (fill in the _ s)

So, the dimensions of the outside border of the walkway are (x + 14) feet (x + 15) feet.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
