4 0

Answer:

(3x - y + 2)(3x + y - 2).

Step-by-step explanation:

9x^2 - y^2 + 4y - 4​

= 9x^2 - (y^2 - 4y + 4)

= 9x^2 - (y - 2)^2

= (3x - (y - 2))(3x + (y - 2)

= (3x - y + 2)(3x + y - 2).

"A ramp rises 1.5 feet for every 18 feet of horizontal distance it covers."
pishuonlain [190]
A ramp rises 1.5 feet <em>for </em>every 18 feet of horizontal distance. Basically the <em>for</em> is what gives it away. You could also just go with the fact that the x variable normally goes left to right (horizontal) and y goes up and down (Rises and falls) which gives you the same thing.
