9 > 19 this has no solution so eliminate this.
b.
3(1 + 4) > 4 + 17
3 × 5 > 4 + 17
15 > 21 no solution.
c.
3(1 + 6) > 6 + 17
3 × 7 > 6 + 17
21 > 23 no solution.
d.
3(1 + 8) > 8 + 17
3 × 9 > 8 + 17
27 > 25 this is a solution.

Answer:
The answer is 25 feet.
Step-by-step explanation:
You have to apply Pythagoras Theorem :
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x
We have : 7x + 5 = 4(x + 5)
3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40
