If a is a nilpotent element of r, a ring with identity, establish that 1 + a is invertible in r.
[hint: (1 + a)-1 = 1-a + a^{2} + + (-1)-1(a)n-1, where (a)^{n}=0]

Big boi and travis scott are performing at the super bowl. travis scott is 62 years younger than twice big boi’s age. the sum of their ages is 70 years old. use b to represent big boi’s age. write and solve an equation.

Having a hard time understanding this question (see attachment).

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)
