Good evening ,
______
Answer:
(4c-d+0.2)² - 10c = 33
___________________
Step-by-step explanation:
(4c-d+0.2)^2-10c
c=3.1, d=4.6
(4(3.1) - 4.6 + 0.2)² - 10(3.1) = (12.4 - 4.6 + 0.2)² - 31 = (7.8 + 0.2)² -31 = 8² - 31 = 64-31 =33.

After, thorough research I believe that there are 265 pine trees and 0 elm trees since decidous and semi-decidous do not grow near conifers.
Answer:
y = ± ![\sqrt{\frac{a-x}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Ba-x%7D%7B2b%7D%20%7D)
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² =
( take the square root of both sides )
y = ± ![\sqrt{\frac{a-x}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Ba-x%7D%7B2b%7D%20%7D)
