Answer:
y = 3x^2 + 12x + 8
Step-by-step explanation:
To rewrite in standard from by expanding the equation using the distributive property.
y= 3 (x+2)^2 - 4
y = 3(x^2 + 4x + 4) - 4
y = 3x^2 + 12x + 12 - 4
y = 3x^2 + 12x + 8
Let x = width of deck needed
(2x + 20)(2x + 50) = 456
Solve for x to find your answer.
2.089 and 2.095 because it goes by thousandths.
