I believe it’s A sorry if it’s incorrect
100-r=99.52
First, add r to both sides.
100-r+r=99.52+r
And then simplify.
100=99.52+r
Then, subtract 99.52 from both sides.
100-99.52=99.52+r-99.52
And simplify.
0.48=r
So,
r=0.48
The sum of the function will be (r – s)(x) = –2x² + x – 3, The difference of the function will be (r – s)(x) = –2x² + x – 3, and The product of the function will be (r × s)(x) = 2x³ – 6x².

<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The functions are given below.
r(x) = x – 3
s(x) = 2x²
The sum of the function will be
(r + s)(x) = x – 3 + 2x²
(r + s)(x) = 2x² + x – 3
The difference of the function will be
(r – s)(x) = (x – 3) – 2x²
(r – s)(x) = –2x² + x – 3
The product of the function will be
(r × s)(x) = (x – 3) (2x²)
(r × s)(x) = 2x³ – 6x²

Answer:
width=18cm
Step-by-step explanation:
perimeter= 2(l+b)
90=2(27+b)
90/2=27+b
45-27=b
b=18cm
Answer:
The number is -6.
Step-by-step explanation:
Variable x = a number
Set up an equation:
3x + 12 = -6
Isolate variable x:
3x = -18
x = -6
Check your work:
3(-6) + 12 = -6
-18 + 12 = -6
-6 = -6
Correct!
