Find the complex conjugate of -18 and 604i-!asap i didn’t understand at ! : (

What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
