Answer:
9x² - 6x - 63
Step-by-step explanation:
Use the FOIL method. FOIL stands for First, Outside, Inside, Last.
Multiply following the FOIL:
3x * 3x = 9x²
3x * -9 = -27x
7 * 3x = 21x
7 * -9 = -63
9x² - 27x + 21x - 63
Combine like terms.
9x² (-27x + 21x) - 63
9x² - 6x - 63
9x² - 6x - 63 is your answer.

Current average = (80 + 93 + 63 + 83 + 83) / 5
= 402 / 5
= 80.4
79 x 6
= 474
what he needs to score on the next test = 474 - 402
= 72
{reassurance = (80 + 93 + 63 + 83 + 83 + 72) / 6
= 474 / 6
= 79}
