$4.40 is the total amount of money spent on the jellybeans.
3x² + 7x - 10
3x² - 3x + 10x - 10
3x(x) - 3x(1) + 10(x) - 10(1)
3x(x - 1) + 10(x - 1)
(3x + 10)(x - 1)
The answer is D.
Answer: x = 7 or x = -8
x² + x - 56 = 0
⇔ x² + 8x - 7x - 56 = 0
⇔ x(x + 8) - 7(x + 8) = 0
⇔ (x - 7)(x + 8) = 0
⇔ x - 7 = 0
or x + 8 = 0
⇔ x = 7 or x = -8
