The two variables are correlated.
While the Moon does indeed turn (i rotates once on its axis in exactly the same time as it takes it to orbit the Earth), this rotation does NOT change the shape of the Moon.
The control variables.
No. Cells do not have the same size nor the same shape.
No.....No two snow flakes are exactly alike. They all have something unique about each and every one of them. There are similar shapes - 3 and 6 sided - and theoretically, you could have many of the same shape. That would be if they fell in the same manner, encountering the same amount of dust and moisture. See attached links.
Same Shape Sally
Congruent
You can't. You can only subtract like terms. Like terms must have exactly the same variables and exponents on the variables.
The are similar
A cube
are congruent.
a line/shape is exactly the same as another line/shape. They have the same length, volume, and angles
means that you can divide the shape in half and both halfs will be the same exactly
simatry is when a shape can be divided into 2 and look exactly the same
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
That refers to terms that have exactly the same combination of variables. For example, in 5xy + x2 - 3xy, the first and last term have the same variables, so they are similar. You can simplify an expression by combining such terms.
No. For purposes of combining "like terms", you need terms that have exactly the same variables, with the same exponents (if there are any).
Any regular or equilateral shape.
