Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64
<h3>
Solving Equations</h3>
The equations can be solved when you replace the variable x for a given value or find the zero of functions.
The question gives:
r(x)=2x-2
s(x)=-x²
First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,
r(x)=2*(-3)-2
r(x)=-6-2= -8
Like r(-3)= -8, you should replace x, in s(x), for -8.
s(x)=-(-8)²
s(x)=-64
Hence, s(r(-3)=-64.

x=12the opposite side of parallelogram are equal
Option D is the correct answer

Further explanation:
Let

The perimeter of a rectangle is given by:

It is also given that:

So we can write as

We also know that The length of the rectangle is three times its width

Putting the value of l in the inequality

Rearranging the terms

Hence, option D is the correct answer.
