Determine which functions have two real number zeros by calculating the discriminant, b2 - 4ac. Check all that
apply
f(x) = x2 + 6x + 8
g(x) = x2 + 4x + 8
h(x) = x2 - 12x + 32
k(x) = x2 + 4x - 1
p(x) = 5x2 + 5x + 4
t(x) = x2 - 2x - 15

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Which equation matches the graph shown ?

Thales was an ancient philosopher familiar with similar triangles. one story about him says that he found the height of a pyramid by measuring its shadow and his own shadow at the same time. if the person is 5-ft tall, what is the height of the pyramid in the drawing?
