Factories both equations:
5(x - 4) / (x + 2)(x - 4)
Then take out the common brackets:
5 / x + 2
Minus 2 from both sides:
3 / x
If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)
Answer:
log9
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
logx - logy = log(
)
log
⇔ nlogx
Given
2(log18- log3) +
log
= 2(log(
) ) + log
= 2log6 + log
= log6² + log
= log36 + log
= log( 36 ×
)
= log9
Circumference,C = 2 πr
C= 2 x 3.14 x 3
C= 18.84 inches
Answer:
x = 
Step-by-step explanation:
Given
x - 5 = 
Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions
6x - 40 = 3 ( add 40 to both sides )
6x = 43 ( divide both sides by 6 )
x =
