Answer:
soil, rocks, and water
Step-by-step explanation:
All 3 of those are abiotic parts
1.First multiply 4(2y) and 4(6) which gives you (8y-24).
2.Then write out the whole problem: (15y-8y-24).
3.Subtract 15y-8y first since they have equal terms. That will give you 7y.
4.Now you have (7y-24).
Hoped this helps!!:-)))
To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:
![x^{2} = 98](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%3D%2098)
Now square root both sides to get
![x = +/- \sqrt{98}](https://tex.z-dn.net/?f=x%20%3D%20%2B%2F-%20%20%5Csqrt%7B98%7D%20)
The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:
![x = - 7 \sqrt{2}](https://tex.z-dn.net/?f=x%20%3D%20-%207%20%5Csqrt%7B2%7D%20)
and
The answer is 8,330
because you have to take 420 and divied it by 18 and youll get 23.33333 then you times it to 357
hope you are satisfied
