4k+44 = 10 k -10
-4k -4k
44 = 6k-10
+10 +10
54=6k
54/6 = 6k/6
9=k hope this helps
We are given " The country recreation department cleared a 3/4 mile long walking trail in Washington Park."
Therefore total distance = 3/4 miles.
"There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. "
Distance of small sign = 1/12 mile.
We need to find the number of signs in 3/4 miles each of 1/12 miles.
<em>In order to find the number of signs, we need to divide total distance by distance of a small sign.</em>
3/4 ÷ 1/12
= 3/4 × 12/1 = 3 × 3
= 9 signs.
<h3>Therefore, 9 signs are needed.</h3>

Step-by-step explanation:
just did it edge hope this helps :))
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
