Let x be the initial width, then the initial length is x+20.
<span>If Elise decreases this length by 8 feet, she will get the new length x+20-8=x+12.
</span>
If Elise increases the width by 10 feet, <span>she will get the new width x+10.
</span><span>
</span><span>The new perimeter will be x+12+x+12+x+10+x+10=4x+44=172, 4x=172-44, 4x=128, x=128÷4, x=32.
</span><span>
</span><span>The initial width is 32 ft and the initial length is 32+20=52 ft.
</span><span>
</span><span>The new width will be 32+10=42 ft, the new length will be 32+12=44 ft.

X 5,10,15,20,25 , Y 25,50,75,100,125 Based on the information in the table, what is the constant of proportionality?
Trava [24]
Answer:
5
Step-by-step explanation:
because its counting up by 5
A=45
Explanation:
A= a+b/2*h
Answer:
Step-by-step explanation:
h(t) = - 16t² + 22t + 6
h = 13.5625 ft
If it takes .1 hours to walk 2/6 miles, then it takes one hour to walk 20/6 miles.
20/6 miles = 3.33 miles
So that is 3.33 miles per hour.
