What is the Pythagorean theorem?

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be expressed as a^2 + b^2 = c^2, where 'a' and 'b' are the lengths of the two shorter sides, and 'c' is the length of the hypotenuse. This theorem is fundamental in geometry and has numerous applications in various fields such as mathematics, engineering, and physics.

How do you factor quadratic expressions?

To factor quadratic expressions, you need to find two binomials that multiply together to give you the quadratic expression. You can factor quadratic expressions of the form ax^2 + bx + c by first finding the factors of a*c that sum to b (the coefficient of the middle term). Once you have identified those factors, you can rewrite the quadratic expression as two binomials in the form (px + q)(rx + s) where p, q, r, and s are the values of the factors you determined.

Describe the process of solving a system of equations using substitution.

To solve a system of equations using substitution, first isolate one variable in one of the equations. Then, substitute the expression for that variable into the other equation. Solve the resulting equation for the remaining variable. Once you have found the value of one variable, substitute it back into one of the original equations to solve for the other variable. Check your solutions by plugging them into both equations to ensure they satisfy both equations.

What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line and b represents the y-intercept, which is the point where the line intersects the y-axis. This form makes it easier to determine the slope and y-intercept of a line and graph it efficiently.

Explain the process of simplifying algebraic expressions.

To simplify algebraic expressions, you must combine like terms by adding or subtracting coefficients that have the same variables and exponents. Additionally, you can perform operations such as distributing and factoring to simplify expressions further. Remember to follow the rules of algebra, such as the order of operations, to ensure that the simplification is done correctly. Ultimately, the goal is to rewrite the expression in its simplest form by reducing redundancy and complexity.

Describe the steps for finding the area of a triangle.

To find the area of a triangle, you need to first measure the base and the height of the triangle. Once you have these measurements, multiply the base by the height and then divide the result by 2. This formula, base multiplied by height divided by 2, will give you the area of the triangle in square units.

What is the difference between an acute angle and an obtuse angle?

An acute angle measures less than 90 degrees, while an obtuse angle measures more than 90 degrees but less than 180 degrees. Acute angles are sharper or narrower, while obtuse angles are wider or more blunt.

How do you find the volume of a rectangular prism?

To find the volume of a rectangular prism, you multiply the length by the width by the height of the prism. The formula for calculating the volume of a rectangular prism is V = l x w x h, where V represents volume, l stands for length, w is the width, and h represents the height of the prism.

Describe the steps for graphing a linear equation on a coordinate plane.

To graph a linear equation on a coordinate plane, start by rewriting the equation in the form y = mx + b, where m represents the slope and b represents the y-intercept. Begin by plotting the y-intercept on the y-axis. Use the slope to find a second point by moving along the x-axis based on the rise over run of the slope. Draw a line connecting the two points to create the graph of the linear equation.

What is the formula for finding the circumference of a circle?

The formula for finding the circumference of a circle is C = 2?r, where C represents the circumference, and r represents the radius of the circle.
