You should keep in mind that when you square both sides of an equation and get an x2-term, you may get extraneous roots.
O A. True
B. False

+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

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
