Sqrt( cos( x))* cos( 200* x)+ sqrt( abs( x))- 0.7* (4- x* x)^ 0.01, sqrt( 9- x^ 2), ‑sqrt( 9- x^ 2)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

The answers 5 so there’s the you need trust me it’s right
