Step-by-step explanation:

inequalities of the type | x | < a have solutions of the form

- a < x < a

then

| 2x + 3 | < 19

- 19 < 2x + 3 < 19 ( subtract 3 from each interval )

- 22 < 2x < 16 ( divide each interval by 2 )

Answer:

d= 4 $\sqrt{2}$ or 5.66

Step-by-step explanation:

(-2,7) and (2,3)

d = $\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }$

d= $\sqrt{(2-(-2))^{2} + (3-7)^{2} }$

d = $\sqrt{16 + 16}$
