If f(x)=-7x-3 and g(x)=√x-16 what is (f °g)(-2)

schepotkina [342]

Answer:

Not possible

Step-by-step explanation:

The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).

g(-2) = √x - 16 = √-2 - 16

This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.

The common factors of 4p3mn2 and 2pm2n3 is

pantera1 [17]

Given:

The given terms are

$4p^3mn^2$ and $2pm^2n^3$

To find:

The common factors of given terms.

Solution:

We have,

$4p^3mn^2$ and $2pm^2n^3$

The factor forms are

$4p^3mn^2=2\times 2\times p\times p\times p\times m\times n\times n$

$2pm^2n^3=2\times p\times m\times m\times n\times n\times n$

The common factors are 2, p, m, n, n. So,

Common factors = $2\times p\times m\times n\times n$

= $2pmn^2$

Therefore, the common factor of given terms is $2pmn^2$ .

D=a+b+c solve for b<br> I need some help

Hoochie [10]

Hi Walker

d=a+b+c

Flip

a+b+c=d

Add -a to both sides

a+b+c-a=d-a

b+c=-a+d

Now add -c to both sides

b+c-c=-a+d-c

b= -a-c+d

I hope that's help:0
