B.
4(1 - 7y) + (4y - 5)(y - 1)
= 4 - 28y + 4y² - 4y - 5y + 5
= 4y² - 37y + 9
C.
3t(t + 1) + (5 + t)(t - 2)
= 3t² + 3t + 5t - 10 + t² - 2t
= 4t² + 6t - 10
D.
(4k - 1)(9 + k) - 9k(10 - 3k)
= 36k + 4k² - 9 - k - 90k + 27k²
= 31k² - 55k - 9
E.
(m + 2)(8 + 3m) - 2(1 - m)(m - 7)
= 8m + 3m² + 16 + 6m - 2(1m - 7 - m² + 7m)
= 3m² + 14m + 16 - 2m + 14 + 2m² - 14m
= 5m² - 2m + 30
