Answer:
The second one, the second to last one, and the last one.
Step-by-step explanation:
The second one is negative because if you add a negative number with a positive number it becomes negative.
The second to last one is zero because if you add a negative and a positive number that is the same number then it becomes zero.
And the last one, they are both simply positive.

325.6 is your answer :
If the number that comes before it is smaller than 5, you keep the number the same. If it’s larger than 5, then you boost it up one. For example, if it was 325.683, you’d round that to 325.7.
Hope that helps!
1. Multiply: (3x+1)(x+2) Answer:3x^2+7x+2
2.Remember to combine all like terms, and FOIL to check if you had factored a trinomial correctly.
To silpify the expression we proceed as follows:
(x+7)/(x^2+4x-21)
Factorizing the given the denominator:
x^2+4x-21
x^2-3x+7x-21
=x(x-3)+7(x-3)
=(x-3)(x+7)
thus plugging back in our expression we have:
(x+7)/[(x-3)(x+7)]
simplifying this we obtain:
1/(x+3)
Answer: 1/(x+3)
