There are 3 sugar cookies.

To find the amount of cookies, multiply 12 by 1/4.

$12 \times \frac{1}{4} = 3$

Answer: OPTION B

Step-by-step explanation:

To solve this problem you must add the areas of each rectangle that form the prism;

The area of a rectangle can be calculated with the formula:

$SA=length*width$

There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:

$SA_{prism}=2(6cm*2cm)+2(3cm*6cm)+2(3cm*2cm)=72cm^{2}$

Given:

The inequality is

$x+19\leq 23$

To find:

The value of x and then graph on the number line.

Solution:

We have,

$x+19\leq 23$

Subtracting 19 from both sides, we get

$x+19-19\leq 23-19$

$x\leq 4$

It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
