How do you verify factoring is correct?

Ivahew [28]

Multiply the factors together. You should get the original expression.

For example, if we are to factor
2x^2 + 4x
we would factor as
2x(x + 2).
Check this by multiplying back in
2x*x + 2x*2 = 2x^2 + 4x
which is what we started with, so we know we are correct.

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ? 1. 6.89 miles/min2 2. 31.8 miles/min2 3

Tom [10]

For this case we have to take into account the following conversions:
$1 mile = 1609.34 meters

1 minute = 60 seconds$
Let's first transform the expression to miles per seconds squared:
$(15.5) * (1 / 1609.34) = 0.009631277 mi / s ^ 2
$
Then, we transform the result to miles per minute squared.
We have then:
$(0.009631277) * (60) ^ 2 = 34.7 mi / min ^ 2
$
Answer:
the rate in miles/min^2 is:
$34.7 mi / min ^ 2$
