The ratio of the area of triangle ABC to triangle A'B'C' is 49/4. What is the scale factor
used to dilate triangle ABC to form triangle
A'B'C'?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

-81 -56 -27 0 81

step-by-step explanation:

$25 becasue a 10 increase would make it from 80 to 50
