Answer:

$Perimeter = 3x + 3$

Step-by-step explanation:

Perimeter of the given triangle in the figure is the sum of all three sides.

The expressions for the 3 sides are given as, $x, (x - 3), (x + 6)$ .

Therefore,

$Perimeter = x + (x - 3) + (x + 6)$

Simplify,

$Perimeter = x + x - 3 + x + 6$

Collect like terms

$Perimeter = x + x + x - 3 + 6$

$Perimeter = 3x + 3$

Answer:

The quality control facility operates for 10 hours each day.

Step-by-step explanation:

The given function models the number of cars that are put through a quality control test each hour at a car production factory.

The given function is

$c(t)= -t^2+8t+20$

We need to find the number of hours does the quality control facility operate each day.

Rewrite the given function it factored form.

$c(t)= -t^2+(10t-2t)+20$

$c(t)= (-t^2+10t)+(-2t+20)$

Taking out the common factors from each parenthesis.

$c(t)= -t(t-10)-2(t-10)$

$c(t)= (t-10)(-t-2)$

$c(t)=-(t-10)(t+2)$

The factored form of given function is c(t)=-(t-10)(t+2).

Equate the function equal to 0 to find the x-intercept.

$0=-(t-10)(t+2)$

$t-10=0\Rightarrow t=10$

$t+2=0\Rightarrow t=-2$

Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

Therefore the quality control facility operates for 10 hours each day.
