Rufina [12.5K]

Answer:

$2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )$

Step-by-step explanation:

$18 {u}^{2} - 50y \\ \\ = 2[9 {u}^{2} - 25y] \\ \\ = 2[(3 {u})^{2} - (5 \sqrt{y} )^{2} ] \\ \\ = 2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )$

Answer:

y = x+1

Step-by-step explanation:

points (0,1) and (2,3)

slope =(y2-y1)/(x2-x1)

While Gary is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown ( I attached below the picture that should have support your question). And If he starts with the assumption that segment DE is parallel to segment BC I am pretty sure that <span>inequality which he will use to contradict the assumption is the first option : </span><span>4:10 ≠ 6:14</span>
