A group of numbers that include 1,2, 3,.....
any number that cannot be expressed as a fraction.
Numbers that include integers, wholes, and natural numbers.
3 + 2 = 2 + 3
Associative Property of Mult. and Addition
The order of the addends or product will not change the sum or the product. (2+3)+5=10,2+(3+5)=10, (2*3)*5=3-,2*(3*5)=30
Multiplying a sum by a number is the same as multiplying each term by the number and then adding (or subtracting ) the products.
f of x
y is the independent variable
y = mx + b
Constant rate of increase or decrease (m) m =slope
f(x)=mx+b, function form (m=3,b=-1) debes resolverlo por m y b
To convert Factored Form to Standard Form you must
must be solved by multiplication

The sum of the measure of two angles is 180 degrees.
Angles whose measure adds up to 90 degrees.
an angel that is greater than 90 degrees
An angle that is 90 degrees (It makes a square in the corner).

A triangle with no congruent sides
Triangle with 2 equal sides and 2 equal angles.
Triangle with a 90° angle
Area = L x W
in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs
A solid shape with one curved surface and two congruent circular bases.
Volume = L x W x H
Volume = 1/3(3.14)R^2xH
A solid shape that is perfectly round like a ball. No faces, edges, or vertices.
