Answer:
3
Step-by-step explanation:
The sum of these two polynomials is - 2 x^2 - 3. the two x variables are additive inverses and -6 x^2 and 4 x^2 equal - 2 x^2 and -3 results from -4 and 1
Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3
It would be D because X^2 is different from 3x you would just multiply X^2 by 1 and 3x by 1 to get x^2+3x
x=11
by simplifying we get x=11
independent
The answer is D (212 degrees)
1st piece: -10<x<0
2nd piece: 0<x<4
3rd piece: 4<x<8
