A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centim

dusya [7]

Answer:

Step-by-step explanation:

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

length + width = 27

So, x + (1/2)x = 27

(3/2)x = 27

x = 27(2/3) = 18 (1/2)x = 9

Answer: length = 18 cm and width = 9 cm

Which of the following is a solution to 2sin^(2)x+sinx-1=0

lukranit [14]

Hello,

$2*sin^2(x)+sin(x)-1=0\\\Delta=1+4*2*1=9=3^2\\sin^2(x)=\frac{-1-3}{4} =-1\ (impossible)\\or\\sin^2(x)=\frac{-1+3}{4} =\dfrac{1}{2}\\sin(x)=\dfrac{\sqrt{2} }{2} \Longrightarrow (x=45^o\ or\ x=135^o)\\or\\sin(x)=-\dfrac{\sqrt{2} }{2} \Longrightarrow (x=315^o\ or\ x=225^o)\\$
