Answer:
5x+2
Step-by-step explanation:
Ok so the expression 5(x+2) is not 5x+2 because you have to use the distributive property. So with that being said:
5(x+2)=5 times x and 5 times 2
so the realest answer is 5x+10 instead of 5x+2
For simple interest
i=prn
where i= interest p=amount invested, r=rate n=time period
i= 970*4 and 1/4 * 2
i= $8245<span />
