From the diagram we obtain two expressions for hypo length and set them equal to one another: 3y = x + 3
Next, set y + 1 = x.
Subst. y + 1 for x in 3y = x + 3: 3y = y + 1 + 3, or 2y =4, or y=2.
Then x= 2 + 1 = 3
So the desired values are x = 3 and y = 2.
Answer:
-1
Step-by-step explanation:
=> -5 + √25 - 4(2)(3) / 4
