Which of the following integrals cannot be evaluated using a simple substitution? a. the integral of the product of x and e raised to the x power, dx
b. the integral of e raised to the power of 2 times x plus 3, dx
c. the integral of the product of x squared and e raised to the x power, dx
d. None of these

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
