Well, since it is  a cube, we know the length of all the sides of 10 cm, so we can create a triangle using the sides of a square and use pythagorean theorem
A²+B²=C²
C being the hypotenuse, or the diagonal we are looking for, so 10²+10² = 200
Then we square root to find C, so √200 = 14.14213562

What is 4x-2y=8 and y=2x+1 using substitution
Setler [38]

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4   or    2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4    or    2x-2x=4+1

0=-5                     0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.

Place the indicated product in the proper location on the grid. (a+b-c)(a+b+c)
aliina [53]

Answer:

The required location on the gird is shown below.

Step-by-step explanation:

Consider the provided expression.

We need to place the indicated product in the proper location on the grid.

First open the parenthesis as shown:

(a+b-c)(a+b+c)=a(a+b+c)+b(a+b+c)-c(a+b+c)

(a+b-c)(a+b+c)=a^2+ab+ac+ab+b^2+bc-ac-bc-c^2

Now add the like terms as shown:

(a+b-c)(a+b+c)=a^2+b^2-c^2+2ab

Hence, the required location on the gird is (a+b-c)(a+b+c)=a^2+b^2-c^2+2ab
