3x⁶y² + 57x⁵y³ + 252x⁴y⁴
= 3x⁴y²(x² + 19xy + 84y²)
= 3x⁴y²(x² + 12xy + 7xy + 84y²)
= 3x⁴y²(x(x + 12y) + 7y(x + 12y))
= 3x⁴y²(x + 12y)(x + 7y)
The dimensions of the closed rectangular box are 14 by 14 by 14
Step-by-step explanation:
Volume of the box will be : l×w×h but l=w,hence volume= w²h
Area of the box is : 2w² + 4hw
Volume,v=w²h=2744----------find height,h
h=2744/w²-------------use this height in the area equation as;
Area=2w²+4hw

Minimizing the area

w=15,to find the height use h=2744/w²
h=2744/14²
h=14
