1 point A box of cookies and muffin contains 12 items. Cookies cost
$3.00 and muffins cost $2.00 each. The whole box costs
$32.00. Let x represent the number of cookies and y the
number of muffins. Write a system of linear equations that can
be used to find the number of cookies and the number of
muffins in the box. *

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

b is the right answer
