Answer:
231525
Step-by-step explanation:
2014 = 200,000
Start of 2015
200,000 x 1.05 = 210,000
Start of 2016
210 x 1.05 = 220,500
Start of 2017
220,000 x 1.05 = 231,525
X² - 3x + 27 = 8x - 3 аdd 3 to both sides ⇒
+ 3 + 3
---------------------------
x² - 3x + 30 = 8x subtract 8x from both sides ⇒<span>
- 8x - 8x
--------------------------
x</span>² - 11x + 30 = 0 ← <span>standard form
</span>
A. Add 3 to both sides and subtract 8x from both sides.
