Question

Using the Pythagorean

Answer 1

• No need of getting confused about using Pythagorean theorem. Question is indirectly saying to apply distance formula
• P(-3,-3)
• Q(7,6)

$\\ \sf\longmapsto PQ=\sqrt{(7+3)^2+(6+3)^2}$

$\\ \sf\longmapsto PQ=\sqrt{(10)^2+(9)^2}$

$\\ \sf\longmapsto PQ=\sqrt{100+81}$

$\\ \sf\longmapsto PQ=\sqrt{181}$

$\\ \sf\longmapsto PQ\approx 13.4units$

Answer 2

Answer:

• 13.5 units

Step-by-step explanation:

Use distance formula:

• $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates:

• $d = \sqrt{(-3-7)^2+(-3-6)^2} =\sqrt{10^2+9^2} =\sqrt{181} =13.5$ rounded
