Answer:

The approximate area is 35 square centimeters

Step-by-step explanation:

we know that

The cross section passing through the diagonal of opposite faces of the cube is a rectangle

so

the approximate area is equal to

A=bh

where

b is the diagonal of a face

h is the length side of the cube

we have

b=7\ cm\\h=5\ cm

substitute

A=7(5)=35\ cm^2

A rectangle is four times as long as it is wide. If its length were diminished by 6 meters and its width were increased by 6 met
valkas [14]

Answer:

Length equals 16 and Width equals 4

Step-by-step explanation:

First let us create an equation. We can use L and W for length and width.

If the length is 4 times the width, then we end up with: L = 4W

It then says, " If its length were diminished by 6 meters and its width were increased by 6 meters, it would be a square."

Since a square has an equal length and width then we end up with:

L - 6 = W + 6

Knowing this we can just substitute the first equation into the second one leaving us with: 4W - 6 = W + 6

We then remove a W from both sides so that the right side is left with a 6, and add 6 to both sides to remove the -6 from the left one.

This leaves us with 3W = 12

W = 4, and if we put that into our first equation, L = 4W, then Length equals 16, and Width equals 4. We can check this by putting it into the 2nd equation. 16 - 6 = 4 + 6.

I need x+y=5 and y=2x-4solved algebraically
schepotkina [342]

Answer:

x = 3; y = 2

Step-by-step explanation:

x + y = 5

y = 2x - 4

<em>Isolate the y in the first equation</em>

y = 5 - x

y = 2x - 4

<em>Substitute the values</em>

5 - x = 2x - 4

<em>Isolate the Variable</em>

9 = 3x

<em>Simplify</em>

3 = x

<em>Plug that into the first equation</em>

3 + y = 5

<em>Subtract 3 from both sides</em>

y = 2
