Can you guys me i got a couple more questions.

The first triangle is acute because its corners are below 90° and not equal to each other.The second triangle is right because it has (at least ) one right corner(90°)

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
