You have to multiply by the complex conjugate so that you can clear the radical from the denominator.
Once you do the multiplication simplify the radical. There's still a common factor in -54, -18, & 75 so divide all those by 3.
Answer: x = 480
Steps: x/2.4 + 39 = 239
Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39
Simplify: x/2.4 = 200
Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4
Simplify: x = 480

Answer:
138
Step-by-step explanation:
The LCD here is 12. Mult. each fraction within the brackets by 12 results in
6[6 + 8 + 9). Perform the addition shown within the parentheses, and then mult. the resulting sum by 6:
6(23) = 138
Answer:
add all of them together then divide bye the number of lines
Step-by-step explanation:
The answer should be 2.5, because you are cutting the value that they gave you in half
