Step-by-step explanation:
a rectangular tabletop has diagonal
$7,800 + 20x = $18,400 can be used to solve this equation, when x is the amount needed per year.
7800 - 7800 + 20x = 18400 - 7800.
20x = 10600. You would need 10,600 over 20 years but, how much would you need per year?
Well 20x/20 = x and 10,600/20 = 530
x = 530. You would need an interest of $530 yearly

Answer: 2*2*2*2*5</h3>
We have four copies of '2' and one copy of '5' multiplied together
This is the same as saying 2^4*5
=========================================
Explanation:
Divide 80 over the smallest prime factor, which is 2
80/2 = 40
Divide that result over 2
40/2 = 20
Keep going until you cannot divide by 2 anymore
20/2 = 10
10/2 = 5
We stop here because 5/2 isn't a whole number. We also stop here since 5 is prime. Circle all the primes that show up and you should have four copies of 2 and one copy of 5.
Therefore: 2*2*2*2*5 = 80
In shorthand, this condenses to 2^4*5 = 80
The factor tree is shown below. Other factor trees are possible.
Answer: 80
Step-by-step explanation: A=LxW.
4x-2=-8
2x-5=-10
-10x-8=80
It would take 200 years (by definition of half-life). 50 is 1/2 of 100.
