[2, 2.5)
(2.5, 3]
step-by-step explanation:
i think its these two not sure [2, 2.5)
x = 2
if sr parallel to ba then the sides bc and ac are in proportion, that is
= ← substitute values
= ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
choice b
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
