Using formula sin^2 x +cos^2 x = 1 you get 1 - cos^2(9x) = sin^2(9x)

so in this way this fraction will be rewrited

sin9x/(1-cos^2(9x) = sin9x / sin^2(9x) = 1/sin9x

Hello There,

P represent the unknown information.

Write an equation to model the problem. 28 ÷ 2 – 4 .

P number, 10, 11, or 12, will solve the equation in Part (b)? Show your work. The reason 10 solves the equation is: 28 ÷ 2 – 4 = 10.

28 ÷ 2 – 4=14-4=10

Hope this helps Have a Wonderful Day! Bye!
