3x^2-18+5=47
3x^2 = 60
x^2 = 20
x = 4.472 , x = - 4.472
Here, 2 1/4 r = 10
9/4 r = 10
r = 10*4 /9
r = 40 / 9
r = 4 4/9
In short, Your Answer would be Option C
Hope this helps!
Answer:
Not possible
Step-by-step explanation:
Which of the following illustrates how to find the difference of 4h^5k and -7hk^5
Takig the difference
4h^5k - (-7hk^5)
= 4h^5k +7hk^5
Collect the like terms
= hk(4h^4+7k^5)
Hence the difference is not possible
The answer to (-5)-3 is -8. I may be wrong but I did the work.
