Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5
The way to find the area of a triangle is A=
![\frac{B*H}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BB%2AH%7D%7B2%7D%20)
if the base is 3 feet longer then the height we can write it like this B=H+3
now we can add it to our area equation
20=
![\frac{H(H+3)}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BH%28H%2B3%29%7D%7B2%7D%20)
20=
![\frac{ h^{2} +3h}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20h%5E%7B2%7D%20%2B3h%7D%7B2%7D%20)
40=
![H^{2}](https://tex.z-dn.net/?f=%20H%5E%7B2%7D%20)

Answer: AB = 6
Step-by-step explanation:
If CD = 12 , AC also = 12
B is the midpoint of AC so one side = 6
AB is one side of AC , so AB = 6
