What is the factored expression of 63x^2-3x-6

Step-by-step explanation:

Suppose a generic quadratic equation

To factor this equation, I need to find its roots. Then we use the quadratic formula of:

and

So, for the equation 63x ^ 2-3x-6 we have:

and

So:

and

Finally the polynomial is:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
