Answer:

First one: 40%

Second one: 30%

Step-by-step explanation:

2/5 is equal to the fraction 4/10 which is also equivalent to 40/100

in a percentage that would be 40% of the dogs are poodles

to find a percentage divide numerator by demonimator and multiply by 100

so divide 12 by 40 and multiply by 100

12/40=0.3

0.4x100=30%

Use the grouping method to factor x³ + x² + 3x+3.

Annette [7]

Answer:

D. $(x + 1)(x^2 + 3)$

Step-by-step explanation:

Hello!

We can group the first two terms and the last two terms.

<h3>Factor by Grouping</h3>

$x^2 + x^2 + 3x + 3$
$x^2(x + 1) + 3(x + 1)$
$(x^2 + 3)(x + 1)$

Factoring by grouping is the process of breaking down larger polynomials to smaller ones to factor. We can then combine like factors.

In the second step, we can see that we can rewrite $x^3 + x^2$ as $x^2(x + 1)$ , as both the two terms share a common factor of $x^2$ . We can pull out $x^2$ from that expression. Similarly, $3x$ and $3$ share a common factor of $3$ , so we can pull that out.
