Answer:
(a) 8√3
Step-by-step explanation:
All of the triangles are similar, so the ratio of hypotenuse to long side is the same for all. Comparing the middle-size triangle to the largest, we have ...
... x/12 = 16/x
... x² = 192 . . . . . . . . . . . . . multiply by 12x; next take the square root
... x = √192 = 8√3 . . . . . . seems to match answer choice (a)
Answer:
FALSE!
a rational number is not a whole number :)
Y = 0
x = ?
y= x^2 -6x +9
0 = x^2 - 6x +9
(x -3)
(x -3)
(x-3)(x-3)
x = 3
y = 3^2 - 6(3) + 9
y = 9 - 18 + 9
y = 18
Answer
x= 3, y = 18
