Answer:
-2 and 13
Step-by-step explanation:
the pattern here is annoying to find, but there is one. the first change is -4, then +6, then -7, then +9. The pattern starts at -4, then after that it increases by 2 and changes from a negative to a positive (and can change the other way). After that change it increases by one and changes from a positive to a negative. Essiently, the pattern is add 2 to the pattern and change the sign, then add 1 to the pattern after that and change the sign, infinitely repeating, with the two after 11 being -2 (gotten from +12 because you add 2 to -10 and change the sign) and 13 (gotten from -13 because you add 1 and change the sign of +12).

Answer:
x=2
Step-by-step explanation:
First use the distributive property on the right side... You should get then have 7x+30 = 2 + 6x + 30
Simplify further by combining like terms to get 7x + 30 = 32 + 6x
Now subtract 6x on both sides (6x - 6x cancels out) to get 1x + 30 = 32
Next subtract 30 from both sides(30-30 cancels out) to get 1x = 2
2 divided by 1 is 2 so x = 2
Answer:
(5x³+3x²-5x+4) + (8x³-5x²+8x+9)
= 5x³+3x²-5x+4 +8x³-5x²+8x+9
= 5x³+8x³+3x²-5x²-5x+8x+4+9
= 13x³-2x²+3x+13
