F(a+2) = 3((a+2) + 5) + 4/(a+2)
= 3a + 21 + 4/(a+2)
Answer: The interest earned on a principal of $646 invested at an interest rate of 5% for three years is $96.9
The simple formula for interest is:

? = 646 * 5/100 * 3
? = 9690/100
? = $96.9

1 3/4 oz is mixed with 1 gallon of water. With 5 2/5 gallons of water, since we multiplied the number of gallons by 5 2/5, we multiply the amount of chemical by 5 2/5 as well:
1 3/4 * 5 2/5
Convert to improper fractions:
7/4 * 27/5 (because 1*4+3=7 and 5*5+2=27)
189/20 = 9 9/20 (because 20 goes into 189 9 times with 9 left over)
Lol its 7th grade math its easy
