You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.

Hope this helps !

padilas [110]

Answer:

A= \frac{4}{3 +  \sqrt{5} }  -  \frac{8}{1 +  \sqrt{5} }  +  \frac{15}{ \sqrt{5} }

=  \frac{4(3 -  \sqrt{5)} }{4}  -  \frac{8(1 -  \sqrt{5} }{ - 4}  +  \frac{15 \sqrt{5} }{5}  = 3 -  \sqrt{5 + 2 - 2 \sqrt{5 + 3 \sqrt{5 = 5} } }
