Answer:

$100x^{4}y^{6}$

Step-by-step explanation:

$(25xy^{3} )(4xy)(x^{2}y^{2})$

Remove parenthesis:

$25xy^{3}*4xyx^{2}y^{2}$

Separate the constants:

$(25*4)xxx^{2}y^{3}yy^{2}$

Let's call the total distance 2a from which we can calculate t1 equivalent to the first half of the distance a/10 similar to t2 is a/15 from which the total time is a/6 . We have the average speed equal to the total distance dduowcngf divided by the total inferred time by 2a/(a/6) which equals 12km/h

(12)2−6(2−23)=<br> will mark brainliest

mr_godi [17]

You would have to do PEMDAS so
(12)2=24
(2-23)=21
(21)6=126
126-24=102
So the answer would be 102 :)
