Answer:
The admixture of words and math symbols must be rewritten to allow processing towards a correct answer.
Step-by-step explanation:
Use brackets [ ] and up carrot symbol (^, obtained by pushing the shift key at same time as 6 key) to rewrite the question. The order of operations called GEMA (Grouping, Exponents, Multiplication and Division from left to right and then Addition and Subtraction from left to right) can only be done once the symbols are placed to match the textbook question. Math is a language and its symbols must be used in place of words to assure the correct result.
sin2x+sinx-2cox-1=0
As we know, Sin 2x =2sinx cosx
2Sinx Cosx+Sinx-2cosx-1=0
Sinx(2cos x+1)-1(2cosx+1)=0
(sinx-1)(2cosx+1)=0
So, either sinx-1=0 or 2cos x+1=0
Sin x=1 or cos x=

Answer:
The width of each bedroom is 12 feet.
Step-by-step explanation:
Each bedroom has 2 walls 13 feet long. That is a total of 8 times 13, which equals 104.
Subtract 104 from 200. That leaves 96 feet to be divided into the 8 widths.
96 ÷ 8 = 12.
12 feet is the width of each bedroom.
