Answer:
234.85
Step-by-step explanation:
This was easy!!!
(The gardener comes 4 times a month... so divide 85.40 by 4 and you will get 21.35. Each time he comes, he gets 21.35 and by the end of the month, he has 85.40. It says he already came 11 times. So 4 + 4 = 8 + another 4 that equals 12. He came only two months and a few weeks. This means multiply 85.40 by 2 so you would get 170.8. It said he came 11 times so substract 11 from 8 and you would get 3. So multiply 21.35 by 3 and get a total of 64.05. Add 170.8 and 64.05 to get 234.85!!! The answer is 234.85 or C!!!!

Answer:
Step-by-step explanation:
Nope, x-√6 is a factor of x^4-36. Let solve the question by factorization method.
x^4 - (√6)^4
x^4 - (√6)^4
(x²)² - (√6²)^²
(x²)² - (√6²)^²
(x² - 6)(x² + 6)
Hence, the required factor forms of equation is (x² - 6)(x² + 6)
Therefore, x-√6 is not a factor of x^4-36.
<u>Formula used while solving the problem :</u>
1. a² - b² = (a + b) (a - b)
2. a^4 - b^4 = ( a² + b²)(a² - b²)
8-7x=22
Subtract 8 from both sides
-7x=14
Divide -7 on both sides
Final Answer: x=-2
