eliminate the arbitrary constants a & b from the partial differential question z^2 =ax^3 +by^3+ab

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

i believe the answer is 323 ft
