A) nth term is n^2 + 1
b) nth term is (n - 1)^2
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)

Basically u do 5÷2=2 1/2
so each person gets 2 slices with 1/2 left
Answer:
3cm
Step-by-step explanation:
V = L * W * H
V = 10 * W * 4
10 * 4 = 40
120 / 40 = 3
W = 3
