Answer:

Subtract (remove) 2 x-tiles from both sides.

x = 5

Step-by-step explanation:

According to the rules of equality, you can add or subtract the same number(s) from both sides of the equal sign. Here, it is convenient to subtract the number of tiles that is on the side with the least number of tiles. That means we want to subtract 2 x-tiles from both sides.

The result of doing that is the answer:

x = 5

Find the length of the segment with endpoints of (3,2) and (-3,-6).

MakcuM [25]

The formula of the length of the segment AB:
$A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$
We have:
$A(3;\ 2)\to x_A=3;\ y_A=2\\\\B(-3;\ -6)\to x_B=-3;\ y_B=-6$
Substitute:
$|AB|=\sqrt{(-3-3)^2+(-6-2)^2}=\sqrt{(-6)^2+(-8)^2}\\\\=\sqrt{36+64}=\sqrt{100}=10$
Answer: B) 10.
