4(5x² - 9x + 7) + 2(-10² + 18x - 13)

  • Distribute 4 inside the parentheses.

20x² - 36x + 28 + 2(-10² + 18x - 13)

  • Find 10 to the power of two.

20x² - 3y6x + 28 + 2(-100 + 18x - 13)

  • Combine like terms inside the parentheses (-100 - 13).

20x² - 36x + 28 + 2(-113 + 18x)

  • Distribute 2 inside the parentheses.

20x² - 36x + 28 + (-226 + 36x)

  • Rewrite as - 226 and + 36x; remove the parentheses.

20x² - 36x + 28 - 226 + 36x

  • Combine like terms. The -36x and 36x cancel each other out.

20x² - 198

  • is your answer.

  • It is not a cross-sectional study because this type of study is used to analyze characteristic of the population depending upon data but this study is not used for disease.
  • It is also not a case-control study as well as prospective cohort study because case-control study is used to observe the new cases of a disease while prospective cohort study is used for determining risks or exposure factors of a disease.
  • It is not a community trial as in which a community is under observation like a city or a country and it is also not a historical prospective cohort study because in this study type, we observe the cohorts (similar objects) with the different qualities. They are studied on the basis of these qualities.
