Answer:

9. 108 cm^2

10. 1,080 m^2

Step-by-step explanation:

9. 2(3x4) = 24/2 = 12 (for right triangles)

8x5 = 40 (base rectangle)

3x8 = 24 (left slanted side of prism)

4x8 = 32 (right slanted side of prism)

12 + 40 + 24 + 32 = 108

10. 2(8 x 15) = 240/2 = 120 (for right triangles)

24 x 15 = 360 (base rectangle)

24 x 17 = 408 (right slanted side of prism)

8 x 24 = 192 (left slanted side of prism)

120 + 360 + 408 + 192 = 1,080

Hello! Mizuki here to help!

The correct answer for problem 9 is B.

The correct answer for problem 10 is also B.

Step-by-step explanation:

<em>Sorry if the work I did is confusing, if you don't get what I did, just comment below and I'll try my best to answer your question!</em>

problem 9 work:

3 x 4 + 5 x 8 + 4 x 8 + 3 x 8 =

12 + 40 + 32 + 24 =

108

problem 10 work:

17 x 24 + 8 x 15 + 15 x 24 + 8 x 24 =

408 + 120 + 360 + 192 =

1080

The midpoint of GH are M(4,3) and D(5,-6). The coordinates of the endpoint are?

Phantasy [73]

Answer:

The endpoint coordinates are (3,12)

Step-by-step explanation: $\frac{5+x^{2} }{2} =4$ $\frac{-6+y^{2} }{2} = 3$

You multiply 4 by 2 which gives you 8 and write the equation $5+x^{2} =8$ then you subtract 5 from 8 to get 3 for the x coordinate.

You multiply 3 by 2 which gives 6 and writhe the equation $-6+y^{2}=6$ then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.

To check use the midpoint formula with coordinates D and your endpoint coordinates $\frac{5+3}{2}=\frac{8}{2} =4 \\$ $\frac{-6+12}{2} =\frac{6}{2} =3$ and you get the answer for the midpoint which is (4,3)
