a(n) = 6n - 7
a(12) = 6(12) - 7
a(12) = 72 - 7
a(12) = 65
The answer is B.
Answer:
(x+1) is a factor with remainder 0.
Step-by-step explanation:
We divide (x+1) into the polynomial
through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial
.

We subtract this from the original
.
This leaves
. We repeat the step above.
.
We subtract this from
. We repeat the step above.

We subtract this from
. We repeat the step above.

We subtract this from
. There is no remainder. This means (x+1) is a factor.
Since she cooked 3/4 of the white rice, there is 1/4 of the white rice that is not cooked. This is equal to 2/8. 2/8+3/8=5/8. This shows that 3/8 of the rice that she bought was cooked. Please mark Brainliest!!!
