-4x - 2

We factor out 4 from expression
1/4 • 4 (-4x -2)

1/4 and 4 cancel out, leaving us with:
1(-4x -2)
-4x - 2

Hope that helps!

We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]

we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get

1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is

-4x + 2

Ymorist [56]

The draw an inscribed polygon inside the circle, the very thing to do is to draw the circle. Thus, the answer is the fourth choice, "Place a point on your paper and then use a compass to construct a circle". After which, we can locate the vertices of the polygon in the circumference of the circle and connect them to make the polygon.

What is the surface area of the triangular prism shown?

Lunna [17]

Answer:

The first step that we are going to do is to solve the area of the top rectangle. We are given a width of 15 cm and a length of 25 cm so we can just multiply them against each other to get the area.

$Area = l * w$

$Area = 25\ cm * 15\ cm$

$Area = 375\ cm^2$

The second side that we are going to solve for is the bottom rectangle. We are given a width of 12 cm and a length of 25 cm so lets just multiply them against each other to get the area.

$Area = l * w$

$Area = 25\ cm * 12\ cm$

$Area = 300\ cm^2$

The next area that we are going to determine is the back rectangle which has a width of 9 cm and a length of 25 cm so lets just multiply them against each other to get the area.

$Area = l * w$

$Area = 25\ cm * 9\ cm$

$Area = 225\ cm^2$

The final area that we have to determine are the side triangles. After determining the area of one triangle we will have to multiply it by 2 to get the area for both of the triangles. We are given a base of 12 cm and a height of 9 cm so lets just use the formula to find the area.

$Area = \frac{1}{2}* b*h$

$Area = \frac{1}{2}* 12\ cm*9\ cm$

$Area = 54\ cm^2$

Multiply it by two to get the area for both of the triangles.

$Area = 54\ cm^2 * 2$

$Area = 108\ cm^2$

Finally, we are onto the last part which is to add up all of the areas and get the surface area after we combine everything.

$Area_{total}=375\ cm^2 + 300\ cm^2 + 225\ cm^2 + 108\ cm^2$

$Area_{total}=1008\ cm^2$

Therefore, our final answer is option B, 1008 $cm^2$

Hope this helps!
