Factor out the GCF. 12ax3 +20bx² + 32cx [?]x([]ax +[ ]bx + [ ]c) Enter

olganol [36]

Answer:

4x(3ax²+5bx+8c)

Step-by-step explanation:

4 is the highest number that fits into all terms of the expression :

So outside the bracket will be 4x :

To find what is inside the bracket we divide each term by 4x

12ax³÷4x = 3ax²

20bx²÷4x=5bx

32cx÷4x=8c

So our final answer is :

4x(3ax²+5bx+8c)

If n^-2 = 1/16, then n could be which of the following?

Zepler [3.9K]

Answer:

The correct choice is

$\boxed{n=4}$

Step-by-step explanation:

The given equation is

$n^{-2}=\frac{1}{16}$

We rewrite the left hand side of the equation as a power(a number to a given exponent.

$n^{-2}=\frac{1}{4^2}$

Recall that;

$\frac{1}{a^m}=a^{-m}$

We apply this property to obtain;

$n^{-2}=4^{-2}$

Since the exponents are the same, the bases are also the same.

Therefore $n=4$
