Answer:
f(x)·g(x) = x³ +x² -2x -2
Step-by-step explanation:
Substitute the function definitions and simplify.
f(x)·g(x)
= (x +1)(x² -2)
= x(x² -2) +1(x² -2)
= x³ -2x +x² -2
f(x)·g(x) = x³ +x² -2x -2
Answer:
x = 12
Step-by-step explanation:
Pythagorean triplet
12,16,20
So, the value of x is 12
x + 256 = 400
