Answer:

-3(-3x + 4) = 9x - 12

Step-by-step explanation:

-3( Ax + 4) = 9x - 12

-3Ax -12 = 9x - 12

Equating coefficients of x terms on both sides :

-3A = 9

A = -3

Therefore, -3(-3x + 4) = 9x - 12

If f(x) = x ² +1 and g(x) =3x+ 1,find [f(4)] ²

guajiro [1.7K]

Answer:

289

Step-by-step explanation:

We don't need $g$ at all for this.

We will need to know $f(4)$ before continuing...

$f(4)$ can be found by replacing $x$ in $f(x)=x^2+1$ with $4$ :

$f(4)=4^2+1$

$f(4)=16+1$

$f(4)=17$

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

Now let's find $[f(4)]^2$ :

$[f(4)]^2$

$[17]^2$

$17(17)$

$289$
