(y + 1)^3 would just be dividing the two
If you want it completely simplified, then it’s the following:
(y + 1)(y + 1)(y + 1)
= y^2 + y + y + 1 (y + 1)
= y^2 + 2y + 1 (y + 1)
= y^3 + y^2 + 2y^2 + 2y + y + 1
= y^3 + 3y^2 + 3y + 1
Answer:
<u>13</u>
<em>Explanation:</em>
11×2-9=13
Since he spent half of his allowance on the movies and he had 11 left, you would multiply 11 x 2. Next, subtract 9 because that is not part of his allowance. You will end out with <u>13.</u>
x^2 - 81 = 0. Add 81 to each side.
x^2 = 81. Take the square root of each side.
x = 9, -9
Before going to B.two-digit addition
