Answer:

No

Step-by-step explanation:

No, because 8x8^58x85 only takes the 8 that it is up against to the fifth power, but (8x8)^5(8x8)5 takes the whole expression to the fifth power.

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!

11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18. Negative 7 x = negative 35 Negative 7 x = 35 7 x = negative 35 7

posledela

Answer:

7 x = -35

Step-by-step explanation:

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35

- 7 x = 35

7 x = negative 35

7 x = 35

In this problem we need to add the equations below i.e.

11x-3y = -17 and -4x+3y=-18

Adding both equations,

11x-3y+(-4x)+3y = -17+(-18)

7x= -35

or

7 x = negative 35

Hence, the correct option is (c).
