Answer:
40 divided by 10
Step-by-step explanation:
![\bf \stackrel{\textit{perimeter of a rectangle}}{P=2(L+w)}~~ \begin{cases} L=length\\ w=width\\ \cline{1-1} P=66 \end{cases}\implies 66=2(L+w) \\\\\\ 33=L+w\implies \boxed{33-w=L} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of a rectangle}}{A=Lw}\qquad \implies 216=Lw\implies 216=(33-w)w \\\\\\ 216=33w-w^2\implies w^2-33w+216=0 \\\\\\ (w-24)(w-9)=0\implies w= \begin{cases} 24\\ 9 \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Bperimeter%20of%20a%20rectangle%7D%7D%7BP%3D2%28L%2Bw%29%7D~~%20%5Cbegin%7Bcases%7D%20L%3Dlength%5C%5C%20w%3Dwidth%5C%5C%20%5Ccline%7B1-1%7D%20P%3D66%20%5Cend%7Bcases%7D%5Cimplies%2066%3D2%28L%2Bw%29%20%5C%5C%5C%5C%5C%5C%2033%3DL%2Bw%5Cimplies%20%5Cboxed%7B33-w%3DL%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20%5Cstackrel%7B%5Ctextit%7Barea%20of%20a%20rectangle%7D%7D%7BA%3DLw%7D%5Cqquad%20%5Cimplies%20216%3DLw%5Cimplies%20216%3D%2833-w%29w%20%5C%5C%5C%5C%5C%5C%20216%3D33w-w%5E2%5Cimplies%20w%5E2-33w%2B216%3D0%20%5C%5C%5C%5C%5C%5C%20%28w-24%29%28w-9%29%3D0%5Cimplies%20w%3D%20%5Cbegin%7Bcases%7D%2024%5C%5C%209%20%5Cend%7Bcases%7D)
now, both values are valid, so if "w" is either one, "L" is the other.
Answer:
$358
Step-by-step explanation:
First you subtract 206 from 248 equaling 42 dollars. Then you add 316 dollars to that equaling $358.
Answer:
A.
Step-by-step explanation:
If you plug g(x) into f(x), you should get 2x - 9
What this question is asking is for you to replace the x in f(x) with the whole equation of g(x) (or vice versa because of the answer choices). Once you plug in one equation into the other, you should find your outcome and your answer.
Composite- 25,26,27,28,30,32,34,28,
Prime- 27,29,31,33
