Diagram/ algebra please help asap needs to be done now

Answer: $20\ cm$

Step-by-step explanation:

For this exercise you need to remember that a Square is defined as a Quadrilateral whose sides are equal in lenght and all its interios angles measure 90 degrees.

Based on that definition, and observing the squarE given in the picture attached, you can write the following equation:

$6x-1=4x+6$

Then, you need to solve for the variable "x" in order to find its value. You get that this is:

$6x-4x-1=6\\\\2x-1=6\\\\2x=6+1\\\\2x=7\\\\x=\frac{7}{2}\\\\x=3.5$

Now, knowing the value of "x" you can susbstitute it into any expression that represents the side of the square, and then you must evaluate in order to find the lenght of the side.

You get:

$(6x-1)\ cm=(6(3.5)-1)\ cm=(21-1)\ cm=20\ cm$

Which of the following sets is NOT closed under addition.

Veronika [31]

Answer:

Step-by-step explanation:

The odd numbers.

Suppose you have 31 and 27 when you add these two together, you get 58 which is not an odd number.

If you need a more mathematical proof, you could do it this way.

2x+1

2x is even. Anything multiplied by 2 is even. When you add 1 you get an odd number

So continue on

2y + 1 is the other number.

2x + 1 + 2y + 1 = 2(x + y) + 2

2 (x + y ) is even. When you add 2 to it, nothing changes. The result is still even.

Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

Alex

So the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Using this, our equation is $\sqrt{(7-(-8))^2+(-1-(-9))^2}$ and we can solve for it as such:

$\sqrt{(7-(-8))^2+(-1-(-9))^2}\\ \sqrt{15^2+8^2}$

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.
