Given f(x) = x^2 - 7x + 12 and g(x) = 3 / (x^2 - 16)
The product of the two functions, <span>(f•g)(x) is equal to:
(x^2 - 7x + 12) * 3 / (x^2 - 16)
To simplify, factor the two polynomials:
x^2 - 7x + 12 = (x - 4 ) (x - 3 )
x^2 - 16 = (x - 4) (x +4)
=> </span><span>(f•g)(x) = (x - 4)(x - 3) * 3 / [ (x - 4) (x +4) ] = 3 (x - 3) / (x + 4)
Answer: 3 (x - 3) / (x + 4)

The correct answer is c I think
1/2+1/6=1/n
4/6=1/n
4n=6
n=6/4=3/2 hours to do the driveways, working together

Answer:
252
Step-by-step explanation:
using a brute force method in c++
#include <stdio.h>
int main(){
int a, b, c, n = 0;
for(a = 1; a <= 9; a++)
for(b = 0; b <= 9; b++)
for(c = 0; c <= 9; c++)
if((a==3 || b==3 || c==3)) n++;
printf("%d\n", n);
}
