55,000,000 is the answer :D

The appropriate choice is ...
C) -x^3 + x^2 - 1
Answer:
C. 5(x-6)=20
Step-by-step explanation:
we can represent the value of x decreased by 6 times 5 as 5(x-6) and then show that that is equal to 20.
Answer:
If we round it to the nearest tenth, our answer would be,
C≈ 17.2 (answer choice C)
Step-by-step explanation:
We will have to use the Pythagorean Theorem to solve this. Since we are not looking for the hypotenuse, but rather the length of one of the legs, we will have to use this,
Let's plug in the values,
Simplify,
Since we know that the opposite of a square is the square root, we are going to apply it.
This tells us that the length of the missing leg would be,
C ≈ 17.2336879396
The answer would be 72x + 12 but I’m not sure but that’s what I got
