X=12.5
If the perimeter is 90
90=3x+3x+15
Combine like terms
90=6x+15
Subtracts 15 from both sides
75=6x
Divide by six to get x by itself
12.5=x

Answer:

Step-by-step explanation:
Given function
is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is
Since the slope is negative, the linear function is decreasing for all x. This means

You ar geven the interval
So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.
At x=-4,
