Let's find the equivalent expressions ~
#1. PROBLEM
![\qquad \tt \dashrightarrow \:11x - 4x + 10x](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A11x%20-%204x%20%2B%2010x)
![\qquad \tt \dashrightarrow \:21x - 4x](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A21x%20-%204x)
![\qquad \tt \dashrightarrow \:17x](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A17x)
#2. PROBLEM
![\qquad \tt \dashrightarrow \:2(1 + 8y)](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A2%281%20%2B%208y%29)
![\qquad \tt \dashrightarrow \:(2 \times 1) + (2 \times 8y)](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A%282%20%5Ctimes%201%29%20%2B%20%282%20%5Ctimes%208y%29)
![\qquad \tt \dashrightarrow \:2 + 16y](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A2%20%2B%2016y)
Arc length = Ф/360 * 2πr
= 30/360 * 2*3.14*10
= 1/12 * 62.8
= 5.23
In short, Your Answer would be 5.23 cm
Hope this helps!
$20 × 1.8 (180% in decimal form) = 36
$36 is how much you spent the 2nd

Answer: They are inverses of each other
==========================================================
Explanation:
We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.
![h(x) = 9x-4\\\\h(f(x)) = 9(f(x))-4\\\\h(f(x)) = 9\left(\frac{x+4}{9}\right)-4\\\\h(f(x)) = x+4-4\\\\h(f(x)) = x\\\\](https://tex.z-dn.net/?f=h%28x%29%20%3D%209x-4%5C%5C%5C%5Ch%28f%28x%29%29%20%3D%209%28f%28x%29%29-4%5C%5C%5C%5Ch%28f%28x%29%29%20%3D%209%5Cleft%28%5Cfrac%7Bx%2B4%7D%7B9%7D%5Cright%29-4%5C%5C%5C%5Ch%28f%28x%29%29%20%3D%20x%2B4-4%5C%5C%5C%5Ch%28f%28x%29%29%20%3D%20x%5C%5C%5C%5C)
and,
![f(x) = \frac{x+4}{9}\\\\f(h(x)) = \frac{h(x)+4}{9}\\\\f(h(x)) = \frac{9x-4+4}{9}\\\\f(h(x)) = \frac{9x}{9}\\\\f(h(x)) = x\\\\](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7Bx%2B4%7D%7B9%7D%5C%5C%5C%5Cf%28h%28x%29%29%20%3D%20%5Cfrac%7Bh%28x%29%2B4%7D%7B9%7D%5C%5C%5C%5Cf%28h%28x%29%29%20%3D%20%5Cfrac%7B9x-4%2B4%7D%7B9%7D%5C%5C%5C%5Cf%28h%28x%29%29%20%3D%20%5Cfrac%7B9x%7D%7B9%7D%5C%5C%5C%5Cf%28h%28x%29%29%20%3D%20x%5C%5C%5C%5C)
Both composite functions lead to x each time.
The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.
Since the ratio is 2/5 then for 25 (which is five 5s) there will be 2 × 5 which is 10
