The system of equations below represents p, the number of photo files, and v, the number of video files Helena uploaded to an on
line storage account. p + v = 650 4p + 9v = 2,925 Which statement describes the solution to the system of equations? Helena uploaded 520 more video files than photo files. Helena uploaded 65 fewer video files than photo files. Helena uploaded 9 times as many photo files as video files.
We know that: <span>3(x-1)^2-162=0 or (x-1)</span>²= 162:3 and (x-1)²= 54 we <span>take the square root of both sides * x-1=</span>√54= 3√6 or x=1+3√6 * x-1= -<span>√54= -3√6 or x=1-3√6 This equation has 2 solutions</span>
