+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

$What is the value of x? enter your answer in the box. x =$

15 + 3x = 3.  Find x.  Subtr. 3 from both sides:  12 = -3x, so x = -4 (answer)
