Which set of numbers does not form a right triangle? A. 14, 48, 50
B. 15, 20, 25
C. 21, 28, 35
D. 27, 35, 46

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

answer:

c) the x-coordinate of the center of the circle increases by 3

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

the answer is 6

hope this !
