Answer:
3(x^y(5x^2y-x³)+25x⁴))
Step-by-step explanation:
15x^2y²-3x^3y+75x⁴
From 15x^2y²-3x^3y only, 3x^y is the common factor
=> 3x^y(5x^2y-x³)+75x⁴
Taking the common factor of the latter expression, 3 shows to be the common factor of all the expression.
=> 3(x^y(5x^2y-x³)+25x⁴)
Answer:
5 units

Answer: He spends 1.5 hours on the first part of trip and 3 hours on the second part of trip
Step-by-step explanation:
Let x = the number of hours for first part
Let y = the number of hours for second part
Concept: speed × time = distance
----------------------------------------------------------------
x+y=4.5
59x+57y=259.5
-----
y=4.5-x
59x+57y=259.5
-----
59x+57(4.5-x)=259.5
59x+256.5-57x=259.5
2x+256.5=259.5
2x=3
x=1.5
4.5-1.5=3 hrs
