Answer:
Step-by-step explanation:
if you need help let me know
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.

Answer:
(C)
Step-by-step explanation:
If A(t) represent the amount of money in a bank account at time t years.
The rate at which the account is increasing is proportional to the amount of money in the account, which is modeled by the differential equation:

First, we solve this differential equation

At the moment when the amount of money in the account is $1000, the amount is increasing at a rate of $50 per year.
When A(t)=$1000, 
Therefore:

Substituting into our result from A(t) above:

16 Feet
it is a pythagreon triple of 6 8 10
so double that and you have 12 16 20
