HELP! If a train is traveling at an avergae rate, r= (2x^2-5x-3)/2x miles per hour, and covers a distance, d=6x^2+3x miles, calculate the time. Use d=rt or t= d/r

the answer is 375 miles

step-by-step explanation:

5/12, or 5: 12

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
