Step-by-step explanation:

You can find the answer to this question by so:

15*14*13*12*11*10*9*8

+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

just sum

10 + 10 = 20
