Acontractor completed the construction of two buildings last year

the keslo building cost 84.5 million
the jones building cost 33.8 million

which statement is true when comparing the costs of the two buildings?

a: keslo cost 2 1/2 times the cost of jones

b: jones cost 2/3 the cost of keslo

c: jones cost 1/2 the cost of keslo

d: keslo cost 3 1/2 times the cost of jones

is the answer d?

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
