What is the first step to answer 3^x+3 = 5^2x-1

answer: its the third option.

step-by-step explanation:

i just took the test.

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.

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
