P(x) = (x + 3)Q(x) + R
<span> P(-3) = (0)Q(x) + R </span>
<span>i P(-3) = R </span>
<span>Now, P(-3) = (-3)⁴ - 9(-3)³ - 5(-3)² - 3(-3) + 4
</span>So
<span>P(-3) = 81 + 243 - 45 + 9 + 4 </span>
<span>=. 292
hope it helps</span>
<em>store y has the better buy.</em>
<em>----</em>
store x -- 3.04 ÷ 3 = $1.01 per bag
store y -- 3.60 ÷ 5 = $0.72 per bag
store z -- $0.78 per bag
store y cost the least so it is the best option.
