From the question,

-2x^2-4x-6

By collecting like terms

-2(x^2-2x-3)

By factoring x^2-2x-3

-2(x^2-3x+1x-3)

Collecting like terms

-2(x^2-3x)+(x-3)

-2(x(x-3)+1(x-3))

88 feet/second = 60 miles/hour. How many feet per second is 1 mile? (Hint: divide both side of the equation by the same amount.)

zalisa [80]

Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

$88 ft/s= 60 miles/hr$

Required

Determine the equivalent of 1 mile/hour

$88\ ft/s= 60\ miles/hr$

Express 60 as 60 * 1

$88\ ft/s= 60 * 1\ mile/hr$

Divide both sides by 60

$\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}$

$\frac{88\ ft/s}{60}= 1\ mile/hr$

Reorder

$1\ mile/hr = \frac{88\ ft/s}{60}$

Divide 88 by 60

$1\ mile/hr = 1.46666666667\ ft/s$

Approximate to 3 significant figures

$1\ mile/hr = 1.47\ ft/s$

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds
