How do you compare like terms?

A common technique for simplifying algebraic expressions. When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x. How do you match like terms? Video quote: We have a pair of like terms in our X terms and we have a pair of like

What is another word for reflection in geometry?

Typically, however, unqualified use of the term “reflection” means reflection in a hyperplane. Some mathematicians use “flip” as a synonym for “reflection”. What are some other words for reflection? synonyms for reflection consideration. contemplation. idea. impression. meditation. observation. opinion. rumination. What is a reflection in geometry? A reflection is an isometry, which means the original

How long can you look at a solar eclipse before going blind?

If you’re tempted to reuse eclipse glasses that are three years or older, they were made before the international safety standard was in place and come with a warning that says you can’t look through them for more than three minutes at a time. These should be discarded, according to the astronomical society. How long

What makes brake pistons retract?

So, when the brake is activated and the piston moves towards the disk, the gasket deforms a little to allow this movement without sliding. When the brake is released, the gasket moves to its original shape and retracts the piston. What causes a brake piston to retract? Square cut seals around the caliper pistons deform

Is a rectangle a strong shape?

Why is a rectangle a strong shape? The shape of a structure affects how strong it is. Rectangles, arches, and triangles are the most common shapes used to build big structures. The weight pushes down on the rectangle and causes the top side to bend. The weight presses down on the arch and is spread

How do you find the perimeter of a 2d shape?

The perimeter of any 2D shape can be found by labelling and adding together each side. Remember to include the length of each side when calculating the perimeter. How do you find the area and perimeter of a 2D shape? Area and Perimeter Formula Area and Perimeter Formula are the two major formulas for any

How do you graph logs?

How do you graph a log function? It can be graphed as: The graph of inverse function of any function is the reflection of the graph of the function about the line y=x . … The logarithmic function, y=logb(x) , can be shifted k units vertically and h units horizontally with the equation y=logb(x+h)+k .

What is the highest magnification mirror?

What is the highest magnification in mirrors? The highest magnification mirrors readily available are 15x to 20x. Is 10x magnification too much? We need a magnification between 5x and 10x. This will allow you to have incredibly precise movements, focusing on individual eyelashes and sharp edges. Any more than this and you’ll miss the big

What do the shepherd moons of Saturn do?

Orbiting at the edges of some of the planet’s main rings, or within gaps between them, these shepherd moons wield enough gravity to herd icy ring particles into place. What is the purpose of the shepherd moons? A shepherd moon (also herder moon or watcher moon) is a small natural satellite that clears a gap

What is the earliest stage of a star?

protostarA protostar is the earliest stage of a star’s life. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts. What are the stages of a star? Seven Main Stages of a Star Giant Gas Cloud. A star originates from a large cloud of gas. …
