Answer:
4.8%
Step-by-step explanation:
First turn it into a fraction. 60/1240. Than we can turn it into an equation 60/1240=x/100. Since 100 is the percent and x is what we need to find. And you now solve to get x=150/31 or 4.8
F(-7)=0
Because that makes the (x+7) factor equal zero and any other factor multiplied by zero also results in zero.
