Use a net to find the surface area of the prism.
eimsori [14]

Answer:

1232 m^2.

Step-by-step explanation:

The net consists of 2 triangles and 3 rectangles.

Area of each triangle = 1/2 * 24*7 .

Area of 1 rectangle =  25 * 19.

The other 2 have areas 24*19 and 7 * 19.

Therefore the surface area of the prism

=  2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19

= 1232 m^2.

5x-4y=19 <br><br> x+2=8<br> Solve simultaneous equation
xeze [42]

Answer:

x = 6, y = 5

Step-by-step explanation:

5x - 4y = 19 -------> equation 1

x + 2 = 8 --------> equation 2

<u>Step 1</u> : Subtract 2 on both sides in equation 2.

x + 2 - 2 = 8 - 2

x = 6

<u>Step 2</u> : Substitute the value of x is equation 1.

5 ( 6 ) - 4y = 19

( 5 * 6 ) - 4y = 19

30 - 4y = 10

<u>Step 3</u> : Subtract 30 on both sides.

30 - 30 - 4y = 10 - 30

- 4y = - 20

<u>Step 4</u> : Multiply - 1 on both sides.

- 1 * - 4y = - 1 * - 20

4y = 20

<u>Step 5</u> : Divide 4 on both sides.

4y / 4 = 20 / 4

y = 5

<u>Hence</u>,

x = 6

y = 5
