Review the work showing the first few steps in writing a partial fraction decomposition. StartFraction 2 x squared + 15 x + 19 Over (x + 4) cubed EndFraction = StartFraction A Over x + 4 EndFraction + StartFraction B Over (x + 4) squared + StartFraction C Over (x + 4) cubed EndFraction 2x2 + 15x + 19 = A(x + 4)2 + B(x + 4) + C 2x2 + 15x + 19 = Ax2 + 8Ax + 16A + Bx + 4B + C Which system of equations can be used to determine the values of A, B, and C?

Dexter read 11 science fiction books and 5 history books. lena read 9 science fiction books and 4 history books. compare the students’ ratios of science fiction books to history books. 1. determine the ratios’ form:    science fiction books to history books 2. write the ratios as fractions:    dexter: 115; lena: 94 3. rewrite with a common denominator. 4. compare. 5. answer the question. determine which shows the correct comparison of the ratios for this problem.
