What are the zeros of the polynomial function f(x) = x3 + x2 − 42x?

Sergeeva-Olga [200]

Answer:

D. -7, 0, 6

Step-by-step explanation:

$x^3+x^2-42x=0$

$x(x^2+x-42)=0$

$x(x^2-6x+7x-42)=0$

$x(x-6)(x+7)=0$

ZEROS:

x = 0

x = 6

x = -7

Hope this helps!

(9r2+3r+6)+(6r2+2r)

Sliva [168]

The terms 9r^2 and 6r^2 are like terms. We add the numbers to the left of the "r^2" to get 9+6 = 15.

So 9r^2+6r^2 becomes 15r^2

The r^2 stays the same. We do not say something like r^2+r^2 = r^4. You might be thinking of r^2 * r^2 = r^(2+2) = r^4

When it comes to adding like terms, we keep the variables the same.

The other pair of like terms are 3r and 2r, so they add to 3r+2r = 5r

--------------------------------------------------------------------------------------------

Overall,

(9r^2+3r+6)+(6r^2+2r) = (9r^2+6r^2)+(3r+2r)+6

(9r^2+3r+6)+(6r^2+2r) = 15r^2+5r+6

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an air

never [62]

The total time taken for round trip will be (f+g)(x) = 14x+11

We have given that

f(x)=4x+13and g(x)=10x-2

<h3>What is the round trip time?</h3>

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

Therefore we get,

$(f+g)(x)=f(x)+g(x)\\ =(4x+13)(10x-3)\\ =4x+13+10x-2\\ =4x+10x+13-2\\ =14x+11$

Hence,The total time taken for round trip will be: (f+g)(x) = 14x+11
