A "rational expression" is a fraction in which the numerator and the denominator are both polynomials. The sum of two such expressions will always produce another such expression, viz.,
<span>p(x)/q(x) + r(x)/s(x) = [p(x)s(x) + q(x)r(x)] / [q(x)*s(x)]. </span>
<span>The numerator and denominator of the sum will both be polynomials when fully expanded</span>

3 to the power of 5 to the power of 2-3 to the power of 0 is 9 because 3 to the power of 0 is one and 2 minus one is one and 2 to the power of one is two and 3 to the power of 2 is 9
Answer: y=5
Step-by-step explanation:
Y=2(4)-3
Y=8-3
Y=5
Since we know that Lane is travelling at 180 steps per minute and that each step is 3.25 feet long, we can easily find his running speed in feet/min. This will be equal to

To find the speed in miles per hour, we just perform a
<em />dimensional analysis. We can use the conversion factors 5280 ft = 1 mile and 60 min = 1 hr to calculate for the speed in miles per hour:
