Answer:
=25a6−36a4
Step-by-step explanation:
=(5a3+−6a2)(5a3+6a2)
=(5a3)(5a3)+(5a3)(6a2)+(−6a2)(5a3)+(−6a2)(6a2)
=25a6+30a5−30a5−36a4
=25a6−36a4

The answer is 19.73 because 19 minus 1.67 is 17.33 and 17.33 plus 2.4 is 19.73
Let the amount invested with 5% interest be x
Therefore, the amount invested with 6% interest will be (6000-x)
It is given that the total interest earned yearly is $337.5. Thus, the equation of interest will be:

Multiplying both sides by 100 we get:


Subtracting both sides by 36000 we get:


Thus, the amount invested at 5% is $2250
Therefore, the amount invested at 6% will be $(6000-2250)=$3750
