Answer:
Therefore x=9
Step-by-step explanation:
Give that,
log x+ log (x-3) = log 54
log x(x-3) =log 54 [
]
x(x-3) = 54
Now expand the above equation to get a quadratic equation
x²-3x=54
⇒x²-9x+6x-54=0
⇒x(x-9)+6(x-9)=0
⇒(x-9)(x+6)=0
⇒x-9=0 or, x+6=0
⇒x=9,-6
Now putting x= -6 in the given expression,
log(-6)+log(-6-9)=log 54.
Since log (-6) does not exist.
Therefore x=9
Answer:
Step-by-step explanation:
3x + 3y = -3 given
3x = -3y - 3 subtract 3y from both sides
x = -y -1 divide everything by 3

Answer: B. Ordinal
Step-by-step explanation:
Given statement : A sports writer predicts the teams that will finish in the top three places in the eastern, central, and western divisions. It means he will predicts the teams that will finish in an order ( from first to third ) . It means the sports writer likely to use ordinal scale.
Hence, B is the right answer.
- An ordinal scale is a level of measurement scale which is used to arrange a data into an order.

A. Similar triangles have equal angles even though they're not the same size that was similar means So then
X^2-5x=4x+36
X^2-5x-4x-36=0
X^2-9x-36=0
(X-12)(x(+3)
X=12. X=3
Angle C and angle F are equal
So 4(12)-5=43
