The function f(x) is a cubic function and the zeros of f(x) are −5, 1 and 2. Assume the leading coefficient of f(x) is 1. Write the equation of the cubic polynomial in standard form.

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.

x= 25/4.

is your answer.

step-by-step explanation:

the answer would be 9 because if it is perpendicular to the green line. the red lines slope is the opposite or reciprocal of the slope of the green line.
