You really do need to learn to read the notation.

1) The last sequence is the only one with a first term of -6 and common ratio of 4.

2) Asked and answered elsewhere. The 1st selection is the only one that reproduces the listed terms.

Answer:x=8 or x=-2

Step-by-step explanation:

log4(x-6) + log4(x)=2

log4(x(x-6))=2

4^2=x(x-6)

4x4=x(x-6)

16=x^2-6x

Arrange the quadratic equation

x^2-6x-16=0

x^2+2x-8x-16=0

x(x+2)-8(x+2)=0

(x-8)(x+2)=0

x-8=0. x+2=0

x=8. x=-2

If sqrt x=-7 then x=-49<br>true or false

natali 33 [55]

False.

IF √x = -7.

Square both sides

(√x)² = (-7)²

x = (-7)(-7)

x = 49

x will equal 49

False is your answer

hope this helps
