Answer:
is that dababy?
Step-by-step explanation:
Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
Answer:
D. last option
Step-by-step explanation:
distribute the exponents outside of parentheses to terms in side to get
x^10 y^20 z^5 on top
and x^2 y^2
then you can subtract the exponents of like terms from numerator and denominator to get
x^8 y^18 z^5
Answer:
Step-by-step explanation:
lets foil it and complete the square
x^2+4x-12x-48=9
x^2-8x=57
(-8/.5)^2=16
(x-4)^2-73
