Factor the expression.

grigory [225]

Hey!

First, let's write the problem,
$4r^2-64$
Factor out the common term, which is 4,
$=4\left(r^2-16\right)$
Then, let's factor this part: $r^2-16$
We are going to factor it using the difference of squares rule.
$=\left(r+4\right)\left(r-4\right)$
Our final factored answer would be,
$=4\left(r+4\right)\left(r-4\right)$

Thanks!

Answer:

183.4286 lbs

Step-by-step explanation:

given that the population of weights for men attending a local health club is normally distributed with a mean of 178-lbs and a standard deviation of 25-lbs.

Total weight in the lift should not exceed 6420 lbs

No of persons limited = 35

Hence average weight of the person that should be below

$\frac{6420}{35} \\=183.4286$

If the average exceeds 183.4286 pounds then the elevator would be considered overloaded.
