Which expression does the graphic represent? A. 7 - 1 B. 7 - ( -1) C. 8 - 1
D. 8 - ( -1)

your answer would be b

the answer, i believe is y-8=1(x+4)

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
