Which of the following is true about these similar triangles dilated by scale factor r? Question 15 options: AB = rDE AB = rEF AB = rAB AB = rDF

wait nvm i know the correct answer now its 100%   81 square feet

~batmans wife dun dun

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.
