A path goes around a triangular park, as shown. a. Find the distance around the park to the nearest yard. The distance is about yards. b. A new path and a bridge are constructed from point Q to the midpoint M of PR¯¯¯¯¯¯¯¯ P R ¯ . Find QM Q M to the nearest yard. QM≈ Q M ≈ yd c. A man jogs from P P to Q Q to M M to R R to Q Q and back to P P at an average speed of 150 yards per minute. To the nearest tenth of a minute, about how long does it take him to travel the entire distance?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

if e is the midpoint of bd, then bd is 14.
