Answer:
13+x
Step-by-step explanation:
all you have to do is 9+4 which is 13 and leave the +x so you get 13+x as your answer
We make the composition of both functions:
f (x) = x ^ 2-1
g (x) = 2x-3
Then:
f (g (x)) = (2x-3) ^ 2-1
Rewriting:
f (g (x)) = 4x ^ 2-12x + 8
The domain of this function is all real numbers.
Equivalently
x: (-inf, inf)
answer:
x: (-inf, inf)
option 1.
Is that supposed to be : y = -x^3 ??
<span>i have the same question </span>
<span>yes it is </span>
<span>so when you write x2 you mean x^2 and 2x is 2^x also ? </span>
<span>is it an exponent
sorry, need ponts

Whats the equation to the question
The width of rectangle is 30, and the length is 69.
<h3>
What is Rectangle?</h3>
A rectangle is a quadrilateral. The opposite sides of a rectangle are equal and parallel to each other. The interior angle of a rectangle at each vertex is 90°. The sum of all interior angles is 360°. The diagonals bisect each other.
Here, lets say x is equal to the width of the room
then, that means the length is (9+2x) So,
198 = 2x+2(9+2x)
Using the distributive property, we know that
2(9+2x)=18+4x
If you don't know what that is, then go search it up :/
so,
198 = 2x+18+4x
198=6x+18
180=6x
30=x
Now, we know that the width is 30,
That means the length is 60+9, Which is 69.
Thus, the width of rectangle is 30, and the length is 69.
