Answer:12.6
Step-by-step explanation:you add all of the numbers then divide by how many numbers you have
y = (x+2)(x-6)(x+7)
<span>(x+2)(x+7)
x^2 - 6x + 2x - 12
x^2 - 4x - 12</span>
<span /><span>(x^2 - 4x - 12)(x + 7)
x^3 + 7x^2 - 4x^2 - 28x - 12x - 84
x^3 + 3x^2 - 40x - 84</span>
<span /><span>y = x^3 + 3x^2 - 40x - 84

Answer: D: 65
Step-by-step explanation:
A nickel is worth 5 cents (which we will write as 0.05).

35 X 0.25 = $8.75
$3.25 + $8.75 = $12
