Hi there
a/(a² - 36) + 2/(a-6) = 1/(a+6)
a/(a+6)(a-6) + 2/(a-6) = 1/(a+6)
Now we need to multiply the terms by (a+6)(a-6)
a + 2(a+6) = 1(a-6)
a + 2a + 12 = a - 6
3a + 12 = a - 6
3a - a = -6 - 12
2a = -18
Divide both sides by 2
2a/2 = -18/2
a = -9
Thus, The correct option is A
I hope that's help !
Good luck !
Answer:
Jack - $28
David - $17
Step-by-step explanation:
Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.
2d-6+d=45
3d-6=45
3d=51
d=$17
We can then substitute back and find 2(17)-6=34-6=$28.
