False

Work Step by Step

Type in the left side of the equation, replacing x with 25. -38(25) + 205 Hit enter, and the result should be -745. Now type in the right side of the equation, replacing x with 25. 25(25) + 120 Hit enter, and the result should be 745. The two sides do not match, which means 25 is not the correct solution to the equation.
