Hey
km/3x-2x= 4
km/3=4+2x
km=3(4+2x)
km=12+6x
km-12=6x
x=km-12/6
so D is the answer
Answer:
5x-10
Step-by-step explanation:
its right
2b 2a
----------------- + -----------------
(b+a)^2 (b^2 - a^2)
2b 2a
= ----------------- + -------------------
(b+a)(b+a) (b+a)(b-a)
2b(b - a) + 2a(b + a)
= ------------------------------------
(b+a)(b+a)(b-a)
2b^2 - 2ab + 2ab + 2a^2
= ---------------------------------------
(b+a)(b+a)(b-a)
2b^2 + 2a^2
= ------------------------
(b+a)(b+a)(b-a)
2(b^2 + a^2)
= ------------------------
(b+a)^2 (b-a)
Answer:
Numerator: 2(b^2 + a^2)
Denominator: (b+a)^2 (b-a)
The next 3 terms would be -162, 468, 1457
You would divide 58 by 4
58/4!
