Will mark as brainliest. multiply the polynomials (a^2 + 3a – 7) and (2a^2 – a + 4). simplify the answer. show your work.

(a²+3a-7)(2a²-a+4) = a²(2a²-a+4) + 3a(2a²-a+4) + (-7)(2a²-a+4)  = (2a⁴ - a³ + 4a²) + (6a³ - 3a² + 12a) + (-14a² + 7a - 28)  = 2a⁴ + (- a³ + 6a³) + (4a² - 3a² -14a²) + (12a + 7a) - 28  = 2a⁴ + 5a³ - 13a² + 19a - 28hope its : )

$22. if larry's profit were to minimize by one for every hour his store were to be closed, we would subtract 30 by 8.

Really long apparently
