3.37 -7(8 + k)
3.38 -7(8 - k)
3.39 x³(x² + 5x + 1)
3.40 -2d(6d + 11)
3.41 -1/2y(2y³ - 8)
3.42 -p(p + q - r)
3.43 2y²(3x + 5z)
3.44 mnp(mn - mp + np)
3.45 -a²b²c²(a + b - c)
3.46 -5x³y⁵(-4x² + xy - 9y + 3y²)

an explanation for each problem would be nice, but if you dont want to/dont feel like it, dont worry about it! thanks for your help in advance​

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan.
