Angie divides the polynomial function f(x)=x3+3x2−7x−21 by (x + 3). What can she conclude from the fact that the remainder is eq

iren [92.7K]

Answer:

See below

Step-by-step explanation:

<u>Given function</u>

f(x)=x³ + 3x²- 7x - 21

<u>We can find its factors:</u>

x³ + 3x² - 7x - 21 =
x²(x + 3) - 7(x + 3) =
(x² - 7)(x + 3)

We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)

Also one of zeros of the function is -3

Answer:

Part 3) Miguel scored 29 points and Alonzo scored 25 points

Part 4) Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

Step-by-step explanation:

Part 3) Let

x ----> the number of points that Miguel scored

y ---> the number of points that Alonzo scored

we know that

$x+y=54$ ----> equation A

$x=y+4$ ----> equation B

substitute equation B in equation A and solve for y

$(y+4)+y=54\\2y=54-4\\2y=50\\y=25$

Find the value of x

$x=25+4=29$

the solution is the point (29,25)

That means ----> Miguel scored 29 points and Alonzo scored 25 points

Part 4) Let

x ----> Morgan's age

y ---> Mr Santos' age

we know that

$x+y=44$ -----> equation A

$x=y-15$ ----> equation B

substitute equation B in equation A and solve for y

$(y-15)+y=44\\2y=44+15\\2y=59\\y=29.5$

Find the value of x

$x=29.5-15=14.5$

the solution is the point (14.5,29.5)

That means ----> Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years
