Aright triangle can be formed using three sides having lengths 18 inches, 24 inches, and

3,4 and 5 are pythagoras triplet  

then you check 18 is 6*3 and 24 is 6*4 so the missed side length will be 6*5=30  

so choice d. is right sure  

hope helped

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
