Answer:
85
Step-by-step explanation:
Note the mother is 3x his age when he is 25 years old. Multiply 3 with 25:
3 x 25 = 75
Ten years pass (35 - 25 = 10). Add 10 to 75:
75 + 10 = 85
When the man is 35 years old, his mother will be 85 years old.

F(x) = x²-81
g(x) = (x-9) -1(x+9)
= (x-9) -x-9
g(x) • f(x)
= [x²-81 ] • [ (x-9) -x-9 ]
=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]
= -18•x² +-81•-18
= -18x²+1458
Answer: 55.25
Step-by-step explanation:
Divide 110.5 by 2 which give you 55.25
So in every hour the car travels at 55.25 miles per hour
