Answer:
K = 3
Step-by-step explanation:
4.5 + 1.5 k = 18 - 3k
Put terms on one side
1.5k + 3k = 18 - 4.5
4.5k = 13.5
k = 3
Answer : <em>3/8 </em>
Step-by-step explanation :
Answer:
B and C
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
solve
3x² - 75 = 0 ( add 75 to both sides )
3x² = 75 ( divide both sides by 3 )
x² = 25 ( take the square root of both sides )
x = ± = ± 5 → B and C
The answer should be 44. hope this helps!
