The intersection of these ranges is 0 < x < 2.39 . B
When the polynomial you’re looking for is divided by 3x + 1, the result is
x^2 – x + 3 with a remainder of 2. To reconstruct the original polynomial,
multiply 3x + 1 by x^2 – x + 3 and add 2:
40 . B
Mark up the figure. Fill in the angles you know:
