I think he will be 50 years old because if u are 10 and he half your age now.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there
