Hello,

$12x^3-2x^2+15x-3\\
=2x^2(6x-1)+3(6x-1)\\
=(6x-1)(2x^2+3)
$

Answer:

Natalie have left with 5 beads.

Step-by-step explanation:

Given:

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace.

Now, to find the beads does Natalie have left.

Total beads Natalie had = 64 beads.

And beads she used to make a bracelet = 24 beads.

So, the remaining beads are = $64-24=40\ beads.$

Now, the beads she used to make a necklace = $40 of \frac{7}{8}$

= $40\times \frac{7}{8}$

= $\frac{280}{8}$

= $35\ beads$

Hence, the beads Natalie have left = remaining beads - beads used to make necklace.

$The\ beads\ Natalie\ have\ left\ =\ 40-35$

$The\ beads\ Natalie\ have\ left\ =\ 5\ beads.$

Therefore, Natalie have left with 5 beads.

Let f(x)=4-x^2, find ( f(x+h)-f(x) ) / h and simplify

Alja [10]

If $f(x)=4-x^2$ , then

$f(x+h)=4-(x+h)^2=4-(x^2+2xh+h^2)=4-x^2-2xh-h^2$

$\dfrac{f(x+h)-f(x)}h=\dfrac{(4-x^2-2xh-h^2)-(4-x^2)}h=-\dfrac{2xh+h^2}h$

Then for $h\neq0$ , we can cancel common terms:

$\dfrac{f(x+h)-f(x)}h=-2x+h$
