55. wendy is standing on the east bank of the south saskatchewan river in saskatoon. she looks at the
historic bessborough hotel on the opposite shore and wonders how far away the building is. wendy
walks 150 m downstream along the bank and stops and places a stick, s, in the bank. then she walks 30
m further downstream. she turns 90° and walks 20 m away from the river until she sees that the stick
she placed on the bank lines up with the hotel across the river. calculate the original distance, x, that
wendy was from the hotel.
hotel
a) 75 m
b) 94 m
c) 100 m
d) 110 m
150 m

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

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
