Step-by-step explanation:
I believe for question 7 the answer is $12,570.99
~ if you are having trouble with problems like these look up compound interest calculator (;
(x2 - ) (x2 + ) = 0
(x2 - 7) (x2 + 2) = 0
(x2 - 7) = 0 and (x2 + 2) = 0
x2 = 7 and x2 = - 2
√x2 = √7 and √x2 = √-2
x = √7 and x = √-2 --> it doesn't exist
When you multiply two square roots together, you basically multiply the numbers within and put a squre root over that.
For example, in this case:
sqrt (5) * sqrt (5) = sqrt (25) = 5
Now that we have 5, we just multiply that to -3 and 7:
5 * -3 * 7 = -105
The answer is -105.
