Answer:
the answer is the first one [3 -12 15 -21]
Step-by-step explanation:
Because 3 times 1 = 3, 3 times -4 = -12, 3 times 5=15, 3 times 7 = -21
because they are in order to get a negative one of them have to be a negative if they both of them where negative it would be positive.

Answer:
7x^3 +11x^2 -5x -8
Step-by-step explanation:
Combine like terms.
(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)
= 7x^3 +11x^2 -5x -8
_____
Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...
(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)
= 7x^3 +9x^2 -3x -8
This is what irrational means:
A number that cannot be expressed as a ratio between two integers and is not an imaginary number. If written in decimal notation, an irrational<span> number would have an infinite number of digits to the right of the decimal point, without repetition.
