now, FOIL and simplify.

25x^2-40x+16-1

25x^2-40x+15

now, plug in -1 for x.

25(-1)^2-40(-1)+15

When you run, your average step length is 42 inches. How many steps would you have to take to run 1 mile (5,280 feet)? Round to

bezimeni [28]

First convert 5,280 ft. into inches.
$5280 \times 12 = 63360$
5280 ft. equals 63360 inches.

Then you divide that by 42
$63360 \div 42 = 1508.57$
If you're rounding to the nearest step then it would take 1509 steps to run 1 mile.
