14/16 or 28/32 but can’t be more simplified
Answer:
Factor by grouping. (3r + 5)(r-3)
Step-by-step explanation:
Area as a function of width, w is:
a(w)=(w-25)^2+625
for maximum area, the width will be:
a'(w)=2(w-25)+0=0
solving for w we egt
2w-50=0
2w=50
w=25 m
given that the perimeter is 100, the length will be:
100=2(L+W)
solving for L we get:
L=50-W
but W=25m
hence
L=50-25=25 m
thus the maximum area will be:
A=L*W=25*25=625m^2

Answer:
n=54
Step-by-step explanation:
Since this is a proportion problem, you have cross mulitply.
7n=9x42
7n=378
n=54
