What is the sum of the polynomials? (-x2 + 9) + (-3x2 – 11x + 4)
0-4x2 - 2x + 4
0 -4x2 - 11x + 13
O 2x2 + 20x + 4
O 2x2 + 11x +

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

i think it is 18

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
