Answer:

Length = 30, width = 20

Step-by-step explanation:

perimeter = 100

length = 10 more than the width

width = ?

100/4 = 25

25 + 25 = 50

50 - 10 = 40/2 = 20

20 +10 = 30 cm

Calculate the surface area and show work :) please help me no links!!
eimsori [14]

Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

<u>Explain:</u>

To find the surface area of a rectangular prism, use this formula:

SA=2lw+2lh+2wh

              or

SA=2(lw+lh+wh)

l-length

w-width

h-height

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

<u>Solve:</u>

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2

------------------------------------------------------------------------------------

<u>Conclude:</u>

I, therefore, believe the area of this rectangular prism is 294 in.²

Find coordinates for x+5y=10 and 3x+5y=0. I need to know how to do this plz explain.
maks197457 [2]

Answer:

(-5,3)

Step-by-step explanation:

<em><u>Method</u></em>

There are several ways you can do this, but one of the best ways is to use a graphing coordinate calendar. The most popular one is Desmos Graphing Calculator. I've attached an image of my work below using the system.

<u><em>Answer</em></u>

As you can see, both equations intersect at a certain coordinate point. This coordinate point is the point you need for the answer. The intersection is (-5,3).

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!
