Write p(x) = 21 + 24x + 6x2 in vertex form.
Citrus2011 [14]

<u>ANSWER</u>

p(x)=-3+6(x+2)^2


<u>EXPLANATION</u>


The given function is


p(x)=21+24x+6x^2


We make the coefficient of x^2 unity by factoring 6 out of the last two terms to obtain;


p(x)=21+6(4x+x^2)


We now add and subtract half the coefficient of x multiplied by a factor of 6 to obtain;


p(x)=21-6(2)^2+6(2)^2+6(4x+x^2)


We now factor 6 out of the last two terms to get;


p(x)=21-6\times 4+6((2)^2+4x+x^2)


p(x)=21-24+6((2)^2+4x+x^2)


The quadratic trinomial in the parenthesis is now a perfect square.


p(x)=-3+6(x+2)^2


Hence the vertex form of the polynomial is


p(x)=6(x+2)^2-3

a person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 secon
larisa [96]

Answer:

20 feet

Step-by-step explanation:

\frac{80 feet}{40 seconds}  = \frac{x feet}{10 seconds}

Simplify \frac{80}{40}

\frac{80}{40} = \frac{2}{1}

Every 1 second, a person will walk 2 feet.

\frac{x}{10} = \frac{20}{10}

X = 20 feet
