Answer:
Step-by-step explanation:
we have
-----> equation A
-----> 
-----> equation B
Substitute equation B in equation A
solve for Y
For n = [1,2,3,4,5] you can evaluate the series as follows:
= 3 + (-6) + (12) + (-24) + (48)
= 63 - 30
= 33
Answer:
3 + 5n
Step-by-step explanation:
This is an arithmetic sequence.
First term = a = 8
Common difference = d =Second term - first term
= 13 - 8
= 5
Nth term = a + (n- 1)*d
= 8 + (n -1) * 5
= 8 + n*5 - 1 *5
= 8 + 5n - 5
= 8 - 5 + 5n
= 3 + 5n
Ans:
The solve for x:
2.41x+3.65(248-x)=622.48
2.41x+3.65×248-3.65x=622.48
2.41x-3.65x+905.2=622.48
-1.24x=622.48-905.2
-1.24x= -282.72
x= -282.72÷ -1.24
x=228

I guess you mean:
X^2 - X - 6 and X^2 - 5X + 6
X^2 - X - 6 = (X + 2)(X − 3)
X^2 - 5X + 6 = (X − 2)(X − 3)
Based on that, their common factor is:
(X - 3)
